Output Response vs. OrientationADXL193Rev. A | Page 7 of 12THEORY OF OPERATIONThe ADXL193 provides a fully differential sensor structure and circuit path, resulting in the industry’s highest resistance to EMI/RFI effects. This latest generation uses electrical feedback with zero-force feedback for improved accuracy and stability. The sensor resonant frequency is significantly higher than the signal bandwidth set by the on-chip filter, avoiding the signal analysis problems caused by resonant peaks near the signal bandwidth.Figure 5 is a simplified view of one of the differential sensor elements. Each sensor includes several differential capacitor unit cells. Each cell is composed of fixed plates attached to the substrate and movable plates attached to the frame.Displacement of the frame changes the differential capacitance, which is measured by the on-chip circuitry.Complementary 400 kHz square waves drive the fixed plates. Electrical feedback adjusts the amplitudes of the square waves such that the ac signal on the moving plates is 0. The feedback signal is linearly proportional to the applied acceleration. This unique feedback technique ensures that there is no net electrostatic force applied to the sensor. The differentialfeedback control signal is also applied to the input of the filter, where it is filtered and converted to a single-ended signal. 05366-005UNIT SENSINGCELLUNITFORCING CELLFigure 5. Simplified View of Sensor Under AccelerationADXL193Rev. A | Page 8 of 12APPLICATIONSPOWER SUPPLY DECOUPLINGFor most applications, a single 0.1 μF capacitor, C DC , adequately decouples the accelerometer from noise on the power supply. However, in some cases, particularly where noise is present at the 400 kHz internal clock frequency (or any harmonic thereof), noise on the supply can cause interference on the ADXL193’s output. If additional decoupling is needed, a 50 Ω (or smaller) resistor or ferrite bead can be inserted in the supply line. Additionally, a larger bulk bypass capacitor (in the 1 μF to 4.7 μF range) can be added in parallel to C DC .SELF-TESTThe fixed fingers in the forcing cells are normally kept at the same potential as that of the movable frame. When the self-test digital input is activated, the voltage on the fixed fingers on one side of the moving plate in the forcing cells is changed. This creates an attractive electrostatic force, which causes the frame to move toward those fixed fingers. The entire signal channel is active; therefore, the sensor displacement causes a change in V OUT . The ADXL193’s self-test function is a comprehensive method of verifying the operation of the accelerometer. Because electrostatic force is independent of the polarity of the voltage across capacitor plates, a positive voltage is applied in half of the forcing cells, and its complement in the other half of the forcing cells. Activating self-test causes a step function force to be applied to the sensor, while the capacitive coupling term is canceled. The ADXL193 has improved self-test functionality, including excellent transient response and high speed switching capability. Arbitrary force waveforms can be applied to the sensor by modulating the self-test input, such as test signals to measure the system frequency response, or even crash signals to verify algorithms within the limits of the self-test swing. The ST pin should never be exposed to voltages greater than V S + 0.3 V . If this cannot be guaranteed due to the systemdesign (for instance, if there are multiple supply voltages), then a low V F clamping diode between ST and V S is recommended.CLOCK FREQUENCY SUPPLY RESPONSEIn any clocked system, power supply noise near the clock frequency may have consequences at other frequencies. An internal clock typically controls the sensor excitation and the signal demodulator for micromachined accelerometers. If the power supply contains high frequency spikes, they may be demodulated and interpreted as an acceleration signal. A signal appears as the difference between the noise frequency and the demodulator frequency. If the power supply spikes are 100 Hz away from the demodulator clock, there is an output term at 100 Hz. If the power supply clock is at exactly the same frequency as the accelerometer clock, the term appears as an offset.If the difference frequency is outside of the signal bandwidth, the filter attenuates it. However, both the power supply clock and the accelerometer clock may vary with time or temperature, which can cause the interference signal to appear in the output filter bandwidth.The ADXL193 addresses this issue in two ways. First, the high clock frequency eases the task of choosing a power supply clock frequency such that the difference between it and the accelero-meter clock remains well outside of the filter bandwidth.Second, the ADXL193 is the only micromachined accelerometer to have a fully differential signal path, including differential sensors. The differential sensors eliminate most of the power supply noise before it reaches the demodulator. Good highfrequency supply bypassing, such as a ceramic capacitor close to the supply pins, also minimizes the amount of interference. The clock frequency supply response (CFSR) is the ratio of the response at V OUT to the noise on the power supply near the accelerometer clock frequency. A CFSR of 3 means that the signal at V OUT is 3× the amplitude of an excitation signal at V DD near the accelerometer internal clock frequency. This is analogous to the power supply response, except that the stimulus and the response are at different frequencies. The ADXL193’s CFSR is 10× better than a typical single-ended accelerometer system.SIGNAL DISTORTIONSignals from crashes and other events may contain high amplitude, high frequency components. These components contain very little useful information and are reduced by the 2-pole Bessel filter at the output of the accelerometer. However, if the signal saturates at any point, the accelerometer output does not look like a filtered version of the acceleration signal. The signal may saturate anywhere before the filter. For example, if the resonant frequency of the sensor is low, the displacement per unit acceleration is high. The sensor may reach the mechanical limit of travel if the applied acceleration is high enough. This can be remedied by locating the accelerometer where it does not see high values of acceleration and by using a higher resonant frequency sensor, such as the ADXL193.Also, the electronics may saturate in an overload condition between the sensor output and the filter input. Ensuring that internal circuit nodes operate linearly to at least several times the full-scale acceleration value can minimize electricalsaturation. The ADXL193 circuit is linear to approximately 8× full scale.ADXL193Rev.

数字滤波器的仿真与实现 - 中英文翻译东南大学成贤学院毕业设计外文翻译电子工程系电子信息工程专业学生姓名：公冶允懋学号： 01408146 设计地点：东南大学成贤学院指导教师：李东新Thal filterWith the information age and the advent of the digital world, digital signal processing has become one of today's most important disciplines and door technology. Digital signal processing in communications, voice, images, automatic control, radar, military, aerospace, medical and household appliances, and many other fields widely applied. In the digital signal processing applications, the digital filter is important and has been widely applied.1、 figures Unit on : Analog and digital filtersIn signal processing, the function of a filter is to remove unwanted parts of the signal, such as random noise, or to extract useful parts of the signal, such as the components lying within a certain frequency range.The following block diagram illustrates the basic idea.There are two main kinds of filter, analog and digital. They are quite different in their physical makeup and in how they work. An analog filter uses analog electronic circuits made up from components such as resistors,capacitors and op amps to produce the required filtering effect. Such filter circuits are widely used in such applications as noise reduction, video signal enhancement, graphic equalisers in hi-fi systems, and many other areas. There are well-established standard techniques for designing an analog filtercircuit for a given requirement. At all stages, the signal being filtered isan electrical voltage or current which is the direct analogue of the physical quantity (e.g. a sound or video signal or transducer output) involved. Adigital filter uses a digital processor to perform numerical calculations on sampled values of the signal. The processor may be a general-purpose computer such as a PC, or a specialised DSP (Digital Signal Processor) chip. The analog input signal must first be sampled and digitised using an ADC (analog todigital converter). The resulting binary numbers, representing successive sampled values of the input signal, are transferred to the processor, which carries out numerical calculations on them. These calculations typicallyinvolve multiplying the input values by constants and adding the products together.If necessary, the results of these calculations, which now represent sampled values of the filtered signal, are output through a DAC (digital to analog converter) to convert the signal back to analog form.Note that in a digital filter, the signal is represented by a sequence of numbers, rather than a voltage or current.The following diagram shows the basic setup of such a system.Unit refers to the input signals used to filter hardware or software. Ifthe filter input, output signals are separated, they are bound to respond tothe impact of the Unit is separated, such as digital filters filter definition. Digital filter function, which was to import sequences X transformation into export operations through a series Y.According to figures filter function 24-hour live response characteristics, digital filters can be divided into two, namely, unlimited long live long live the corresponding IIR filter and the limited response to FIR filters. IIRfilters have the advantage of the digital filter design can use simulation results, and simulation filter design of a large number of tables mayfacilitate simple. It is the shortcomings of the nonlinear phase; Linear phaseif required, will use the entire network phase-correction. Image processingand transmission of data collection is required with linear phase filtersidentity. And FIR linear phase digital filter to achieve, but an arbitrarymargin characteristics. Impact from the digital filter response of the unitscan be divided into two broad categories : the impact of the limited response(FIR) filters, and unlimited number of shocks to (IIR) digital filters.FIR filters can be strictly linear phase, but because the system FIRfilter function extremity fixed at the original point, it can only use thehigher number of bands to achieve their high selectivity for the same filterdesign indicators FIR filter called band than a few high-IIR 5-10 times, thecost is higher, Signal delay is also larger. But if the same linear phase, IIRfilters must be network-wide calibration phase, the same section also increasethe number of filters and network complexity. FIR filters can be used toachieve non-Digui way, not in a limited precision of a shock, and into thehomes and quantitativefactors of uncertainty arising from the impact of errors than IIR filtersmall number, and FIR filter can be used FFT algorithms, the computationalspeed. But unlike IIR filter can filter through the simulation results, thereis no ready-made formula FIR filter must use computer-aided design software(such as MATLAB) to calculate. So, a broader application of FIR filters, andIIR filters are not very strict requirements on occasions.Unit from sub-functions can be divided into the following four categories :(1) Low-filter (LPF); (2) high-filter (HPF); (3) belt-filter (BPF); (4) toprevent filter (BSF).The following chart dotted line for the ideals of the filter frequencycharacteristics : A1(f) A2(f)1 10 fc2 f 0 fc2 f (a)(b) A3(f) A4(f)1 10 fc1 fc2 f 0 fc1 fc2 f (c)(d) (a)LPF (b)HPF (c)BPF (d)BSF2、 MATLAB introducedMATLAB is a matrix laboratory (Matrix Laboratory) is intended. In addition to an excellent value calculation capability, it also provides professional symbols terms, word processing, visualization modeling, simulation and real-time control functions. MATLAB as the world's top mathematical software applications, with a strong engineering computing, algorithms research, engineering drawings, applications development, data analysis and dynamic simulation, and other functions, in aerospace, mechanical manufacturing and construction fields playing an increasingly important role. And the C language function rich, the use offlexibility, high-efficiency goals procedures. High language both advantages as well as low level language features. Therefore, C language is the most widely used programming language. Although MATLAB is a complete,fully functional programming environment, but in some cases, data and procedures with the external environment of the world is very necessary and useful. Filter design using Matlab, could be adjusted with the design requirements and filter characteristics of the parameters, visual simple, greatly reducing the workload for the filter design optimization.In the electricity system protection and secondary computer control, many signal processing and analysis are based on are certain types Yeroskipou and the second harmonics of the system voltage and current signals (especially at D process), are mixed with a variety of complex components, the filter has been installed power system during the critical components. Current computer protection and the introduction of two digital signal processing software main filter. Digital filter design using traditional cumbersome formula, the need to change the parameters after recalculation, especially in high filters,filter design workload. Uses MATLAB signal processing boxes can achieve rapid and effective digital filter design and simulation.MATLAB is the basic unit of data matrix, with its directives Biaodashi mathematics, engineering, commonly used form is very similar, it is used to solve a problem than in MATLAB C, Fortran and other languages End precision much the same thing. The popular MATLAB 5.3/Simulink3.0 including hundreds of internal function with the main pack and 30 types of tool kits (Toolbox). kits can be divided into functional tool kits and disciplines toolkit. MATLAB tool kit used to expand the functional symbols terms, visualization simulation modelling, word processing and real-time control functions. professionaldisciplines toolkit is a stronger tool kits, tool kits control, signal processing tool kit, tool kits, etc. belonging to such communicationsMATLAB users to open widely welcomed.

Filters are electronic circuits that selectively allow certain frequencies to pass through while attenuating others. They are used in a wide range of applications, from audio and video processing to power supplies and communication systems. In this essay, we will explore the different types of filters, their characteristics, andtheir applications.Types of Filters。
Filters can be classified into two main categories: passive filters and active filters. Passive filters use only passive components such as resistors, capacitors, and inductors to filter out unwanted frequencies. Active filters, on the other hand, use active components such as transistors, operational amplifiers, and digital signal processors to amplify, attenuate, or shift frequencies.Passive Filters。
Passive filters are the simplest type of filters and are widely used in audio and video processing. They can be further classified into three types: low-pass filters, high-pass filters, and band-pass filters.Low-pass filters allow low frequencies to pass through while attenuating high frequencies. They are commonly used in audio systems to filter out noise and unwanted signals. High-pass filters, on the other hand, allow high frequencies to pass through while attenuating low frequencies. They are used in applications such as radio communication and audio equalization.Band-pass filters allow a range of frequencies to pass through while attenuating frequencies outside the range. They are used in applications such as radio frequency (RF) communication and audio processing.Active Filters。

ANALOGFILTER库函数说明
二、模拟量标定库AnalogFilter Library模拟量标定库就是指AnalogFilter.lib中的一些库函数。
2.1 CUT功能块功能描述：把输入值进行预处理，调整斜率，消除两端非线性影响。
调整效果见图：功能块如下图：输入：（1）Input，UINT型，要处理的信号。
（2）PAR_InputILowLimit，UINT型，用来控制输出的下限。
当Input<=256*PAR_InputILowLimit 时输出为0。
（3）PAR_InputHighLimit，UINT型，用来控制输出的上限。
当Input>=256*PAR_InputHighLimit 时输出就为256*PAR_InputHighLimit。
输出：（1）Output，UINT型，处理完的信号。
（2）LowLimit，BOOL型，Input<=256*PAR_InputILowLimit时LowLimit为TRUE。
（3）HighLimit，BOOL型，Input>=256*PAR_InputHighLimit时HighLimit为TRUE。
(*CUT是一个FBD，INPUT:0~65535, 当INPUT<=PAR_InputlLowLimit*255或INPUT>=PAR_InputHighLimit*255时，OUTPUT输出为0，相应的LOWLIMIT 和HIGHLIMIT就有报警输出，当PAR_InputlLowLimit*255<INPUT<PAR_InputHighLimit*255,OUTPUT输出0～65535。
CUT是EPEC模拟量处理库函数中的一个，用户其实可以根据自己的实际需要自己定义一个FBD，比如我们可以自己做一个FBD使其输出范围为0～500等等。
*)2.2 HP功能块功能描述：设置一个死区，把死区以内的值都设为0。
功能如图：功能块如下图：输入：（1）Input，UINT型，输入信号。

according to EN50178-1, PD II, OVC III•Operating temperature is real ambient temperature around the driver core •Environmental conditions see Technical Explanation•Do not touch the transformersFootnotesFootnote Description1)The rated peak and average output current are valid over the full operating temperature range.2)The rated maximum switching frequency is valid over the full operating temperature range.3)Repetitive peak voltage across the semiconductor power rails.4)The maximum DC-Link voltage is limited by creepage and clearance distances(according to EN50178-1, PD II, OVC III).5)Test Conditions: ACrms, 2s, input to output.6)If using power semiconductor modules with gate charges >2.5µC, the buffer capacitance of the driver's secondarysides and primary side has to be adjusted according to the corresponding Technical Explanation.7)Time between the driver detects an error at the secondary side until the primary side reports an error at the interface.8)Time between the driver receives an external error signal at the primary side until the driver turns off its outputs at thesecondary side.9)The interlock dead time prevents the two outputs from being activated simultaneously. The dead time generationstarts with each turn-off command at the driver's primary side. The interlock dead time generation could bedeactivated via pin 'CFG_IDT'.10)The jitter is defined as the maximum deviation of the switching signal propagation delay time at constantenvironmental conditions. The signal transfer deviation t jittter(ana) is valid if analog filtering is selected via pin'CFG_FLT' and the interlock dead time, generated by the controller, is longer than the interlock dead time which isensured by the driver itself.11)Minimum time for which the driver is in error state.12)The driver detects a desaturation event, when one of its outputs is in on-state and the applied voltage at thecorresponding V CE-monitoring input (pin 'VCE_IN') exceeds the reference voltage for V CE-monitoring. As long as theblanking time has not been elapsed, the desaturation detection is deactivated. The blanking time is adjustable via the'CFG_VCE' pin.13)The driver's output switches to high-resistance state, when the output is in off-state and the applied voltage at thecorresponding 'CLMP_IN' pin exceeds the input threshold voltage V ITH(clamp). The output returns to off-state when theapplied voltage at pin 'CLMP_IN' falls below the input threshold voltage V ITL(clamp).14)Test condition: 8000V, pulse according to EN50178-1.15)The partial discharge extinction voltage in this data sheet is defined as peak voltage.16)Conditions: T op = 40°C; full load. Theoretical consideration according to SN 29500.17)All external circuits, except the V CE reference voltage adjustment, have to be supplied via pin 'PWR_VS_P_OUT' withrespect to pin 'PWR_VS_N_OUT'. The rated average output current is reduced by the supply current of theseexternal circuits.34Pin description - primary side Pin description - secondary side - TOP PIN Signal FunctionSpecificationsX10:01PWR_GND Ground potentialfor power supply and digital signals To be connected to ground X10:02CFG_IDTInterlock dead time configuration15V logic; 150k Ω (pull-up)LOW = 2µs interlock dead time HIGH = No interlock dead time X10:03nERR_OUT Error outputOpen collector output; max. 18V/15mA (external pull-up resistor needed)LOW = Error HIGH = No errorX10:04nERR_IN Error input15V logic inverted; 150k Ω/10nF (pull-up)LOW = External error HIGH = No external errorX10:05CFG_ERRError behavior configuration in case of secondary side error15V logic; 150k Ω (pull-down)LOW = Both outputs switch offHIGH = Outputs switch off with next turn-off signal at the corresponding input X10:06CFG_FLTFilter configuration for switching signals 15V logic; 150k Ω (pull-down)LOW = Analog filter (t SPS(ana))HIGH = Digital filter (t SPS(dig))X10:07TOP_INSwitching signal input (TOP)15V logic; 33k Ω/0.01nF (pull-down)LOW = TOP switch off HIGH = TOP switch onX10:08BOT_IN Switching signal input (BOT)15V logic; 33k Ω/0.01nF (pull-down)LOW = BOT switch off HIGH = BOT switch on X10:09PWR_VS Driver power supply Stabilized +15V ±4%X10:10PWR_VSDriver power supplyStabilized +15V ±4%PIN Signal FunctionSpecificationsX100:01CFG_VCE V CE -monitoring reference voltage External voltage divider needed X100:02VCE_INV CE -monitoring inputExternal blocking diode neededX100:03PWR_VS_P_OUT Power supply output, positive voltage Equal to V G(on)17)(external buffer capacitors can be connected)X100:04nERR_INExternal error input15V logic inverted; 150k Ω/0.01nF (pull-up)LOW = External error HIGH = No external errorX100:05TOP_ON On signal path to TOP semiconductor External gate resistor needed(in consideration of I out(avg), I out(peak), V G(on))X100:06TOP_OFF Off signal path to TOP semiconductor External gate resistor needed(in consideration of -I out(avg), -I out(peak), V G(off))X100:07CLMP_INV CE -clamping input150k Ω/0.01nF (pull-down)In case of activated TOP_OFF:LOW = TOP_OFF equal to V G(off)HIGH = TOP_OFF floatingX100:08PWR_GND Ground potential forpower supply and digital signalsReference potential for gate voltages (emitter/source of power semiconductor)X100:09TOP_SOFTOFF SoftOff signal path to TOP semiconductor External gate resistor neededX100:10PWR_VS_N_OUTPower supply output, negative voltageEqual to V G(off)17)(external buffer capacitors can be connected)Pin description - secondary side - BOTPIN Signal Function SpecificationsX200:01CFG_VCE V CE-monitoring reference voltage External voltage divider neededX200:02VCE_IN V CE-monitoring input External blocking diode neededX200:03PWR_VS_P_OUT Power supply output, positive voltage Equal to V G(on)17)(external buffer capacitors can be connected) X200:04nERR_IN External error input15V logic inverted; 150kΩ/0.01nF (pull-up)LOW = External errorHIGH = No external errorX200:05BOT_ON On signal path to BOT semiconductor External gate resistor needed(in consideration of I out(avg), I out(peak), V G(on)) X200:06BOT_OFF Off signal path to BOT semiconductor External gate resistor needed(in consideration of -I out(avg), -I out(peak), V G(off)) X200:07CLMP_IN V CE-clamping input150kΩ/0.01nF (pull-down)In case of activated BOT_OFF:LOW = BOT_OFF equal to V G(off)HIGH = BOT_OFF floatingX200:08PWR_GND Ground potentialfor power supply and digital signals Reference potential for gate voltages (emitter/source of power semiconductor)X200:09BOT_SOFTOFF SoftOff signal path to BOT semiconductor External gate resistor neededX200:10PWR_VS_N_OUT Power supply output, negative voltage Equal to V G(off)17)(external buffer capacitors can be connected)5This is an electrostatic discharge sensitive device (ESDS) due to international standard IEC 61340.*IMPORTANT INFORMATION AND WARNINGSThe specifications of SEMIKRON products may not be considered as guarantee or assurance of product characteristics ("Beschaffenheitsgarantie").

模拟滤波器转化为数字滤波器的方法
模拟滤波器转化为数字滤波器的方法Transforming an analog filter into a digital filter involves several methods and considerations. The process requires an understanding of the characteristics of both analog and digital filters, as well as the advantages and limitations of each type. To begin with, it is important to consider the fundamental differences between analog and digital filters. Analog filters process continuous signals, while digital filters process discrete signals. This fundamental difference significantly impacts the way in which the two types of filters are designed and implemented.将模拟滤波器转化为数字滤波器涉及到几种方法和考虑因素。
这个过程需要理解模拟和数字滤波器的特性，以及每种类型的优点和局限。
首先，重要的是考虑模拟和数字滤波器之间的基本区别。
模拟滤波器处理连续信号，而数字滤波器处理离散信号。
这种基本区别显著影响了两种类型滤波器的设计和实现方式。
One common approach to converting an analog filter to a digital filter is through a process called discretization. Discretization involves sampling the input signal and converting it into a sequence ofnumbers that can be processed by a digital filter. This method allows for the characteristics of the analog filter to be preserved in the digital domain, ensuring that the desired filtering effects are maintained. However, it is important to note that discretization can introduce issues such as quantization error and aliasing, which must be carefully managed in the design of the digital filter.一个常用的方法是通过一种称为离散化的过程将模拟滤波器转化为数字滤波器。

一般情况下，要实现一个传递函数，在设计电路的时候有许多选择，没有确定的答案，同 时，在实现一阶电路的时候可能会遇到一些元器件取值不现实的问题，因此需要根据实际情况 调整元器件的参数。下面举一个例子来说明。

但是有个问题，就是未知参量太多而方程太少，这样设计起来选择的方法非常多，下面讨论两 种常用的方法： （一） 、等电容等电阻法： R1 = R2 = R ， C1 = C 2 = C ，这样

实现一个传递函数为 T ( s ) = 得出：
5 的电路。按照表 1.1 中的第一种方法，我们不难 s / 2000 + 1
Y2 / Y1 = s / 2000 ， ( R A + RB ) / RB = 5 ，因此我们容易得到图 1.3 所示电路图：

（2）
其中， μ = ( R A + R B ) / R B 在上面二阶电路的设计中我们选择特定器件值来设定自然频率 ω 0 和阻尼系数 ζ 。通过比 较（2）式的分母和标准形式： ( s / ω 0 ) + 2ζ ( s / ω 0 ) + 1 不难得出：
（5）
这样得到的高通滤波器和低通滤波器有相同的通带增益和截止频率。

我们讨论具有一定要求增益响应函数 T ( jω ) 情况下如何设计滤波器。设计过程应该从构 建一个符合要求的传递函数开始，可以将传递函数变成如下形式：
T ( S ) = T1 ( s ) × T2 ( S ) × T3 ( s ) × " × Tn ( s )
（1）
其中，Tk ( S ) 是只具有一个极点和至多一个零点的一阶传递函数。阶数越高，过渡带下降越陡， 性能越好。一阶传递函数可以通过一阶电路来实现，下表 1.1 介绍几种常见的一阶电路图。 一阶电路 传递函数

电话机所发出的任何一个信号没有检测之前无法确定它究竟包含哪两个信号，但是我们还 是可以知道其中一个来自低频组，另外一个来自高频组。我们要做的第一步是利用低通滤波器 和高通滤波器将高频分量和低频分量分离出来，当然，低通滤波器和高通滤波器的截止频率都 应该介于低频组的最高频率和高频组的最低频率之间。当然，我们要根据实际情况来确定截止 频率。经过这一步，我们可以得到低通滤波器输出的信号是低频组的四个不同频率信号中间的 一个，而高通滤波器输出的信号是高频组的三个不同频率信号中间的一个。剩下的工作是确定 低频组和高频组分别是哪个信号，要解决这个问题，我们可以通过图 1.2 所示方法，就是将低 通滤波器后面分成四路，每一路都接上一个带通滤波器，而高通滤波器之后分成三路，每一路 也都接上一个带通滤波器。当然每个带通滤波器的通频带都不一样，每一个带通滤波器只能让 该信号组的一个信号通过。这样，7 个带通滤波器的输出只有两个有正弦信号输出，其中一个 来自低频组，另外一个来自高频组。这些信号通过后面连接的检测器检测到之后，就能判断究 竟是按了哪个键。 2. 模拟滤波器的设计 滤波电路是根据频域特性要求来设计的，主要任务归结到了实现期望的增益响应函数。滤 波器设计的方法非常多。一般情况下，给定一个增益响应函数，可以设计出许多不同的电路来 实现。有无源设计方法：主要是利用电容、电感和电阻来实现，也可以用有源设计方法：主要 是利用电阻、电容和运算放大器。相对于无源滤波器，有源 RC 滤波器有如下优点： 1、 有源滤波器能够很方便的调整频率响应的增益和衰减。

(3)、带通和带阻滤波器
前面介绍的一阶和二阶电路很容易实现低通和高通滤波器，在此基础上如我我们使用级连 （串联和并联）的方法就可以很容易得到带通和带阻滤波器，如图 1.6 和 1.7 所示。
高通滤波器 ωCHP 低通滤波器 ωCLP
高通滤波器 ωCHP
低通滤波器 ωCLP

带通滤波器
图 1.7
带阻滤波器
其中，低通滤波器的截止频率(ωCLP)高于高通滤波器的截止频率(ωCHP),低通滤波器提供上 截止频率，高通滤波器提供下截止频率。带阻滤波器中，低通滤波器的截止频率要低于高通滤 波器的截止频率。
注意：表中是将截止频率归一化了，具体应用时令：s=s/ωC 高通滤波器设计 高通滤波器传递函数能够通过低通滤波器原形的复频域变量 s 的变换直接得到。如果一个 低通滤波器的传递函数为 TLP(s)，通带增益为 TMAX，截止频率为ωC，那么对应的高通滤波器 的传递函数 THP(s)可以定义为：
2 THP ( s ) = TLP (ω C / s)
2
2、 有源传递函数能够分为多级来实现，每一级可以独立设计，最后将它们级连起来就可 以实现整个系统函数。 3、 有源滤波器实现起来尺寸更小，也更便宜，因为他们不需要电感，应用在低频方面， 电感尺寸通常比较大。 这里我们介绍一些滤波器的设计方法，主要是在幅频特性上来实现系统传递函数，相频特 性在这里不作考虑。通常采用的模拟滤波器有 Butterworth 函数、Chebyshev 函数、Bessel 函 数、椭圆滤波器函数等。 (1)、一阶电路设计

按键式电话给我们提供了一个频域信号处理的例子。按键式键盘如图 1.1 所示。按一个键 发送两个正弦波的和，其中一个正弦波来自低频组(697Hz，770Hz，852Hz，941Hz)，另一个来

自高频组(1209Hz，1336Hz，1447Hz)。例如，按 3 键发送正弦波 697Hz 和 1447Hz 两个正弦波。 键盘上的每一个按键都唯一地对应两个频率组合，我们可以将其认为是编码。反过来，接收方 要完成的事就变成了译码，就是要知道该信号究竟包含了哪两个频率分量。 滤波器是从频域的角度上来分离信号的。通过滤波器，可以让某些频带上的信号通过而拒 绝某些频带上的信号，图 1.2 列出了解码按键式电话信号的过程。
