Designers reading this series can lean about the possibilities of DSP to deal with analog signals and where to find additional sources of information and assistance.4.1 What Is DSP?In brief, DSPs are processors or microcomputers whose hardware, software, and instruction sets are optimized high-speed numeric processing applications-an essential for processing digital data representing analog signals in real time. What a DSP does is straightforward. When acting as a digital filter, for example, the DSP receives digital values based on samples of a signal, calculates the results of a filter function operating on these values, and provides digital values that represent the filter output; it can also provide system control signals based on properties of these values. The DSP’s high-speed arithmetic and logical hardware is programmed to rapidly execute algorithms modeling the filter transformation.The combination of design elements a arithmetic operators, memory handling, instruction set, parallelism, data addressing that provide this ability forms the key difference between DSPs and other kinds of processors. Understanding the relationship between real-time signal and DSP Calculation speed provides some background on just how special this combination is .The real-time signal comes to the DSP asa train of individualsamples from an analog-to-digital converter (ADC) .To do filtering in real-time, the DSP must complete all the calculations and operations required for processing each samples (usually updating a process involving many previous samples ) before the next sample arrives. To perform high-order filtering of real-world signals having significant frequency content calls for really fast processors.4.2 Why Use a DSP?To get an ideal of the type of calculations of DSP dose and get an ideal of how an analog circuit compares with a DSP system , one could compare the two systems in terms of a filter function. The familiar analog filter uses resistors ,capacitors,inductors ,amplifiers .It can be cheap and easy to assemble ,but difficult to calibrate,modify, and maintain a difficulty that increases exponentially with filter order .For many purposes, one can more easily design ,modify,and depend on filters using a DSP because the filter function on the DSP is software-based, flexible ,and repeatable.Further,to createflexibly adjustable filter s with higher-order response requires only software modifications,with no additional hardware unlike purely analog circuits .An ideal bandpass filter,with the frequency response shown in Fig.4.1,would have the following characteristics:? a response within the passband that is completely flat with zero phase shift? infinite attenuation in the stopband.Useful additions would include:? passband tuning and width control? Stopband rolloff controlAs Fig.4.1 shows, an analog approach using second-order filters would require quite a few staggered high-Q sections; the difficulty of tuning and adjusting it can beimagined.With DSP software ,there are two basic approaches to filter design : finite impulse response (FIR) and infinite impulse response(IIR) .The FIR filter's time response to an impulse is thestraightforward weighted sum of the present and a finite number of previousinput samples. Having no feedback,its response to a given sample ends when the sample reaches the "end of the line "(Fig. 4 . 2). An FIR filter's frequency response has no poles, only zeros. The IIR filter , by comparison, is called infinite because it is a recursivefunction:its output is a weighed sum of inputs and outputs. Since itis recursive , its response can continue indefinitely . An IIR filter frequency response has both poles and zeros. .The x(s) are the input samples, y(s) are the output samples, a(s) are input sample weighings, and b(s) are sample weighings. Nis thepresent sample time, and M and N are the number of samples programmed (the filter's order). Note that the arithmetic operations indicatedfor both types are simply sums and products in potentially great number. In fact ,multiply-and-add is the case for many DSP algorithms that represent mathematical operations of great sophistication and complexity.Approximating an ideal filter consists of applying a transferfunction with appropriate coefficients and a high enough order , or number of taps (considering the train of input samples as tappeddelay line). Fig. 4.3shows the response of a 90-tap FIR filter compared with sharp-cutoff Chebyshev filters of various orders. The90-tap example suggests how close the filter can come toapproximating an ideal filter. Within a DSP system, programming a 90-tap FIR filter like the one in Fig. 4.3 is not a difficult task. By comparison, it would no be cost-effective to attempt this level of approximation with a purely analog circuit. Another crucial point in favor of using a DSP to approximate the ideal fillter is long-term stability. With an FIR (or an IIR having sufficientresolution to avoid truncation-error buildup), the programmable DSP achieves the same response,time after time. Purely analog filter responses of high order areless stable with time.Mathematical transform theory and practice are the core requirementfor creating DSP application and understanding their limits. This article series walks through a few signal-analysis and-processing examples to introduce DSP concepts. The series also provides references to texts for further study and identifies software tools that case the development of signal-processing software.4.3 Sampling Real-world SignalsReal-world phenomena are analog the continuously changing energylevels of physical processes like sound, light, heat, electricity, magnetism, A transducer converts these levels into manageableelectrical voltage and current signals, and an ADC sampling frequency, of the ADC is critically important in digital processing processingof real-world signals.This sampling rate is determined by the amount of signal information that is needed for processing the signal adequately for a given application. In order for an ADC to provide enough samples to accurately describe the real-world signal, the sampling rate must beat least twice the highest-frequency component of the analog signal. For example, to accurately describe an audio signal containing frequencies up to 20kHz, the ADC must sample the signal at a minimumof 40kHz. Since arriving signal can easily contain component frequencies above 20kHz (including noise), they must be removedbefore sampling by feeding the signal through a low-pass filter, is intend to remove the frequencies above 20kHz that could corrupt the converted signal.However, the anti-aliasing filter has a finite frequency rolloff, so additional bandwidth must be provided for the filter's transition band. For example, with an inputsignal bandwidth of 20kHz, one might allow 2 to 4kHz of extra bandwidth.Figure 4.4 depicts the filter needed to reject any signals with frequencies above half of a 48kHz sampling rate.Second sample .The time between samples is the time budget for the DSP to preform all processing tasks.For the audio example ,a 48kHz sample rate corresponds to a 20.833vs sampling interval. Fig.4.5 relates the the analog signal and digital sample rate .图Next consider the relation between the speed of the DSP andcomplexity of the algorithm (the software containing the transform or other set of numeric operations ).Complex algorithm require more processing tasks.Because the time between samples is fixed ,thehigher complexity calls for faster processing .For example ,suppose that the algorithm requires 50 processing operations to be performed。

An Introduction to Data Acquisition
When data from a number of independent signal sources must be processed by the same microcomputer or communications channel, a multiplexer is used to channel the input signals into the A/D converter. Multiplexers are also used in reverse, as when a converter must distribute analog information to many different channels. The multiplexer is fed by a D/A converter which continually refreshes the output channels with new information.
句中from monolithic ICs to potted modules意为“从单块集成 电路到封装模块”， rack-mounted modules意为“安于机架 上的模块”， manual scaling and null adjustments意为“手动 缩放和零位调整” 。
An Introduction to Data Acquisition
句中Multiplexers意为“多路器” 。
An Introduction to Data Acquisition
In many systems, the analog signal varies during the time that the converter takes to digitize an input signal. The changes in this signal level during the conversion process can result in errors since the conversion period can be completed some time after the conversion command. The final value never represents the data at the instant when the conversion command is transmitted. Sample hold circuits are used to make an acquisition of the varying analog signal and to hold this signal for the duration of the conversion process. Sample-hold circuits are common in multichannel distribution systems where they allow each channel to receive and hold the signal level.

This interdisciplinary field, at the nexus of electronics, computer science, and mechanical engineering, plays a crucial role in enhancing productivity, ensuring safety, and optimizing processes across diverse industries.The Foundation of AutomationAt its core, ICE revolves around the design, installation, maintenance, and optimization of measurement systems, control systems, and automation technologies. These systems are the backbone of any automated industrial process, enabling precise monitoring, data acquisition, and dynamic adjustment of process variables in real-time. From temperature and pressure sensors to complex programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems, ICE professionals integrate these components to create intelligent, self-regulating systems.Boosting Productivity and EfficiencyOne of the most significant contributions of ICE to modern industries lies in its ability to significantly boost productivity and efficiency. By automating repetitive and labor-intensivetasks, companies can allocate human resources more effectively, focusing on strategic decision-making and innovation. Furthermore, precise control over process parameters ensures consistent product quality, reducing waste and enhancing overall operational efficiency. This, in turn, leads to cost savings and increased competitiveness in the global market.Ensuring Safety and ReliabilitySafety is paramount in any industrial setting, and ICE plays a vital role in mitigating risks and ensuring the reliable operation of systems. By implementing robust safety instrumentation systems (SIS) and integrating failsafe control strategies, ICE professionals ensure that even in unforeseen circumstances, processes can be safely shut down or diverted to prevent accidents. Additionally, real-time monitoring and predictive maintenance capabilities enable early detection of potential issues, further enhancing system reliability and reducing downtime.Facilitating Smart ManufacturingAs the Industry 4.0 revolution gains momentum, ICE becomes even more indispensable. Smart factories, powered by the Internet of Things (IoT), big data analytics, and advanced automation technologies, rely heavily on ICE expertise to design and implement intelligent systems that can learn, adapt, and optimize processes autonomously. From cyber-physical systems to autonomous mobile robots, ICE professionals are at the forefront of transforming traditional manufacturing into agile, flexible, and sustainable smart manufacturing ecosystems.ConclusionIn conclusion, Instrumentation and Control Engineering is a cornerstone of modern industrial automation, driving innovation, enhancing productivity, ensuring safety, and facilitating the transition to smart manufacturing. As technology continues to evolve, the demand for skilled ICE professionals will undoubtedly grow, making this field an exciting and rewarding career choice for those passionate about leveraging technology to shape the future of industries worldwide. By continually advancing our knowledge and embracing emerging technologies, we can unlock even greater potential in automation, creating safer, more efficient, and sustainable industrial processes for generations to come.中文对照翻译：标题：仪表与控制工程在现代工业自动化中的作用在21世纪初，技术进步正在重塑我们生活的方方面面，仪表与控制工程（ICE）是一门关键学科，推动着现代工业自动化的发展。
