滤波器主要参数与特性指标
滤波器的主要参数（Definitions）：中心频率（Center Frequency）：滤波器通带的频率f0，一般取f0=（f1+f2）/2，f1、f2为带通或带阻滤波器左、右相对下降1dB或3dB边频点。
窄带滤波器常以插损最小点为中心频率计算通带带宽。
截止频率（Cutoff Frequency）：指低通滤波器的通带右边频点及高通滤波器的通带左边频点。
通常以1dB或3dB相对损耗点来标准定义。
相对损耗的参考基准为：低通以DC处插损为基准，高通则以未出现寄生阻带的足够高通带频率处插损为基准。
通带带宽（BWxdB）：指需要通过的频谱宽度，BWxdB=（f2-f1）。
f1、f2为以中心频率f0处插入损耗为基准，下降X（dB）处对应的左、右边频点。
通常用X=3、1、0.5 即BW3dB、BW1dB、BW0.5dB 表征滤波器通带带宽参数。
分数带宽（fractional bandwidth）=BW3dB/f0×100[%]，也常用来表征滤波器通带带宽。
插入损耗（Insertion Loss）：由于滤波器的引入对电路中原有信号带来的衰耗，以中心或截止频率处损耗表征，如要求全带内插损需强调。
纹波（Ripple）：指1dB或3dB带宽（截止频率）范围内，插损随频率在损耗均值曲线基础上波动的峰-峰值。
带内波动（Passband Riplpe）：通带内插入损耗随频率的变化量。
1dB带宽内的带内波动是1dB。
带内驻波比（VSWR）：衡量滤波器通带内信号是否良好匹配传输的一项重要指标。
理想匹配VSWR=1：1，失配时VSWR<1。
对于一个实际的滤波器而言，满足VSWR<1 BWdBBWdBdiv>在入射波和反射波相位相同的地方，电压振幅相加为最大电压振幅Vmax ，形成波腹；在入射波和反射波相位相反的地方电压振幅相减为最小电压振幅Vmin ，形成波节。
其它各点的振幅值则介于波腹与波节之间。

降低系统噪声转换情况：
共模噪声转换成差模噪声会降低系统的抗干扰能力!
差模噪声转共模噪声会增加系统往外辐射的能量价格节省将近85%!
优化PCB面积：＞70%!
器件体积平均减少73%! 满足超薄设计需求！
直接取代共模电感+2-3个滤波电容的传统L-C滤波电路！
具有更良好的温度和振动特性,直接达到125 ℃车规级。
用于DC-DC滤波优势明显。
与传统滤波电路28:1噪声幅值抑制；
频域噪声抑制最大达41dBuVZ;
可同时降低传导/辐射发射。
1BDL EMI滤波器的特色
虽然BDL的电原理图和一般的EMI滤波器区别不大，它不过是由两个Y电容和一个X 电容构成的一般EMI滤波器而已，见图1a)所示。

滤波器主要参数与特性指标-滤波器的主要性能参数
滤波器的主要参数（Definitions）：之袁州冬雪创作中心频率（Center Frequency）：滤波器通带的频率f0，一般取f0=（f1+f2）/2，f1、f2为带通或带阻滤波器左、右相对下降1dB或3dB边频点.窄带滤波器常以插损最小点为中心频率计算通带带宽.截止频率（Cutoff Frequency）：指低通滤波器的通带右边频点及高通滤波器的通带左边频点.通常以1dB或3dB相对损耗点来尺度定义.相对损耗的参考基准为：低通以DC处插损为基准，高通则以未出现寄生阻带的足够高通带频率处插损为基准.通带带宽（BWxdB）：指需要通过的频谱宽度，BWxdB=（f2-f1）.f1、f2为以中心频率f0处拔出损耗为基准，下降X（dB）处对应的左、右边频点.通常常使用X=3、1、0.5 即BW3dB、BW1dB、BW0.5dB 表征滤波器通带带宽参数.分数带宽（fractional bandwidth）=BW3dB/f0×100[%]，也常常使用来表征滤波器通带带宽.拔出损耗（Insertion Loss）：由于滤波器的引入对电路中原有信号带来的衰耗，以中心或截止频率处损耗表征，如要求全带内插损需强调.纹波（Ripple）：指1dB或3dB带宽（截止频率）范围内，插损随频率在损耗均值曲线基础上动摇的峰-峰值.带内动摇（Passband Riplpe）：通带内拔出损耗随频率的变更量.1dB带宽内的带内动摇是1dB.带内驻波比（VSWR）：衡量滤波器通带内信号是否杰出匹配传输的一项重要指标.抱负匹配VSWR=1：1，失配时VSWR<1.对于一个实际的滤波器而言，知足VSWR<1 BWdBBWdBdiv>在入射波和反射波相位相同的地方，电压振幅相加为最大电压振幅Vmax ，形成波腹；在入射波和反射波相位相反的地方电压振幅相减为最小电压振幅Vmin ，形成波节.其它各点的振幅值则介于波腹与波节之间.这种合成波称为行驻波.驻波比是驻波波腹处的电压幅值Vmax与波节处的电压幅值Vmin之比.回波损耗（Return Loss）：端口信号输入功率与反射功率之比的分贝（dB）数，也等于|20Log10ρ|，ρ为电压反射系数.输入功率被端口全部吸收时回波损耗为无穷大.回波损耗，又称为反射损耗.是电缆链路由于阻抗不匹配所发生的反射，是一对线自身的反射.从数学角度看，回波损耗为-10 lg [(反射功率)/(入射功率)].回波损耗愈大愈好，以减少反射光对光源和系统的影响.阻带抑制度：衡量滤波器选择性能好坏的重要指标.该指标越高说明对带外干扰信号抑制的越好.通常有两种提法：一种为要求对某一给定带外频率fs抑制多少dB，计算方法为fs处衰减量As-IL；另外一种为提出表征滤波器幅频响应与抱负矩形接远程度的指标——矩形系数（KxdB<1），KxdB=BWxdB/BW3dB，（X可为40dB、30dB、20dB等）.滤波器阶数越多矩形度越高——即K越接近抱负值1，制作难度当然也就越大.延迟（Td）：指信号通过滤波器所需要的时间，数值上为传输相位函数对角频率的导数，即Td=df/dv.带内相位线性度：该指标表征滤波器对通带内传输信号引入的相位失真大小.按线性相位响应函数设计的滤波器具有杰出的相位线性度.特性指标1、特征频率：1）通带截频fp=wp/（2p）为通带与过渡带鸿沟点的频率，在该点信号增益下降到一个人为规定的下限；2）阻带截频fr=wr/（2p）为阻带与过渡带鸿沟点的频率，在该点信号衰耗下降到一人为规定的下限；3）转折频率fc=wc/（2p）为信号功率衰减到1/2（约3dB）时的频率，在很多情况下，常以fc作为通带或阻带截频；4）固有频率f0=w0/（2p）为电路没有损耗时，滤波器的谐振频率，复杂电路往往有多个固有频率.2、增益与衰耗滤波器在通带内的增益并不是常数.1）对低通滤波器通带增益Kp一般指w=0时的增益；高通指w→∞时的增益；带通则指中心频率处的增益；2）对带阻滤波器，应给出阻带衰耗，衰耗定义为增益的倒数；3）通带增益变更量△Kp指通带内各点增益的最大变更量，如果△Kp以dB为单位，则指增益dB值的变更量.3、阻尼系数与品质因数阻尼系数是表征滤波器对角频率为w0信号的作用，是滤波器中暗示能量衰耗的一项指标.阻尼系数的倒数称为品质因数，是*价带通与带阻滤波器频率选择特性的一个重要指标，Q= w0/△w.式中的△w为带通或带阻滤波器的3dB带宽，w0为中心频率，在很多情况下中心频率与固有频率相等.品质因数电学和磁学的量.暗示一个储能器件（如电感线圈、电容等）、谐振电路中所储能量同每周期损耗能量之比的一种质量指标；串联谐振回路中电抗元件的Q值等于它的电抗与其等效串联电阻的比值；元件的Q值愈大，用该元件组成的电路或网络的选择性愈佳.在串联电路中，电路的品质因数Q有两种丈量方法，一是根据公式 Q=UL/U0=Uc/U0测定，Uc与UL分别为谐振时电容器C与电感线圈L上的电压；另外一种方法是通过丈量谐振曲线的通频带宽度△f=f2-f1，再根据Q=f0/(f2-f1)求出Q值.式中f0为谐振频率，f2与f1是失谐时，亦即输出电压的幅度下降到最大值的1/√2（=0.707)倍时的上、下频率点.Q值越大，曲线越尖锐，通频带越窄，电路的选择性越好.4、活络度滤波电路由许多元件构成，每一个元件参数值的变更都会影响滤波器的性能.滤波器某一性能指标y对某一元件参数x变更的活络度记作Sxy，定义为：Sxy=(dy/y)/(dx/x).该活络度与丈量仪器或电路系统活络度不是一个概念，该活络度越小，标记着电路容错才能越强，稳定性也越高.5、群时延函数当滤波器幅频特性知足设计要求时，为包管输出信号失真度不超出允许范围，对其相频特性∮(w)也应提出一定要求.在滤波器设计中，常常使用群时延函数d∮(w)/dw*价信号经滤波后相位失真程度.群时延函数d∮(w)/dw越接近常数.。

accessible.Read and follow these instructions when connecting and using your Public Information Display:• Unplug the display if you are not going to use it for an extensive period of time.• Unplug the display if you need to clean it with a slightly damp cloth.The screen many be wiped with a dry cloth when the power is off.However,never use alcohol,solvents or ammonia-based liquids.• Consult a service technician if the display does not operate normally when you have followed the instructions in this manual.• The casing cover should be opened only by qualified service personnel.• Keep the display out of direct sunlight and away from stoves or any other heat sources.• Remove any object that could fall into the vents or prevent proper cooling of the display’s electronics.• Do not block the ventilation holes on the cabinet.• Keep the display dry.T o avoid electric shock,do not expose it to rain or excessive moisture.• If turning off the display by detaching the power cable,wait for 6 seconds before re-attaching the power cable for normal operation.• T o avoid the risk of shock or permanent damage to the set do not expose the display to rain or excessive moisture.• When positioning the display,make sure the power plug and outlet are easily accessible.• IMPORTANT:Always activate a screen saver program during your application.If a still image in high contrast remains on the screen for an extended period of time,it may leave an ‘after-image’or ‘ghost image’on the front of the screen.This is a well-knownphenomenon that is caused by the shortcomings inherent in LCD technology.In most cases the afterimage will disappear graduallyover a period of time after the power has been switched off.Be aware that the after-image symptom cannot be repaired and is notcovered under warranty.BDL3210Q / BDL4210Q / BDL4610Q Regulatory InformationCE Declaration of ConformityWe declare under our responsibility that the product is in conformity with the following standards:•

that may cause undesiredoperation.BDL3210Q / BDL4210Q / BDL4610QPolish Center for Testing and Certification NoticeThe equipment should draw power from a socket with an attached protection circuit (a three-prong socket).All equipment that works together (computer, display,printer,and so on) should have the same power supply source.The phasing conductor of the room’s electrical installation should have a reserve short-circuit protection device in the form of a fuse with a nominal value no larger than 16 amperes (A).T o completely switch off the equipment,the power supply cable must be removed from the power supply socket,which should be located near the equipment and easily accessible.A protection mark “B” confirms that the equipment is in compliance with the protection usage requirements of standards PN-93/T-42107 and PN-89/E-06251.Electric, Magnetic and Electronmagnetic Fields (“EMF”)1.We manufacture and sell many products targeted at consumers,which,like any electronic apparatus,in general have the ability to emit and receiveelectromagnetic signals.2.One of our leading Business Principles is to take all necessary health and safety measures for our products,to comply with all applicable legalrequirements and to stay well within the EMF standards applicable at the time of producing the products.3.We are committed to develop,produce and market products that cause no adverse health effects.4.We confirm that if its products are handled properly for their intended use,they are safe to use according to scientific evidence available today.5.We play an active role in the development of international EMF and safety standards,enabling us to anticipate further developments in standardizationfor early integration in its products.BDL3210Q / BDL4210Q / BDL4610Q Information for U.K. onlyWARNING - THIS APPLIANCE MUST BE EARTHED.Important:This apparatus is supplied with an approved moulded 13A plug.T o change a fuse in this type of plug proceed as follows:1.Remove fuse cover and fuse.2.Fit new fuse which should be a BS 1362 5A,A.S.T.A.or BSI approved type.3.Refit the fuse cover.If the fitted plug is not suitable for your socket outlets,it should be cut off and an appropriate 3-pin plug fitted in its place.If the mains plug contains a fuse,this should have a value of 5A.If a plug without a fuse is used,the fuse at the distribution board should not be greater than 5A.NOTE:T he severed plug must be destroyed to avoid a possible shock hazard should it be insertedinto a 13A socket elsewhere.How to connect a plugThe wires in the mains lead are coloured in accordance with the following code:BLUE - “NEUTRAL” (“N”)BROWN - “LIVE” (“L”)GREEN & YELLOW - “EARTH” (“E”)1.The GREEN & YELLOW wire must be connected to the terminal in the plug which is marked withthe letter “E” or by the Earth symbol or coloured GREEN or GREEN & YELLOW.2.The BLUE wire must be connected to the terminal which is marked with the letter “N” or colouredBLACK.3.The BROWN wire must be connected to the terminal which marked with the letter “L” orcoloured RED.Before replacing the plug cover,make certain that the cord grip is clamped over the sheath of the lead - not simply over the three wires.BDL3210Q / BDL4210Q / BDL4610QChina RoHS中国电子信息产品污染控制标识要求 (中国RoHS法规标示要求) 产品中有毒有害物质或元素的名称及含量部件名称有毒有害物质或元素铅(Pb)汞(Hg)镉(Cd)六价铬(Cr 6+)多溴联苯(PBB)多溴二苯醚(PBDE)外壳O O O O O O液晶面板X X O O O
