电源滤波器是由电容、电感和电路组成的滤波电路。滤波器可以对电源线中特定频率的频点或该频点以外的频率进行有效滤除，得到一个特定频率的电源信号，或消除一个特定频率后的电源信号。滤波器在通信技术、测量技术、控制系统等领域有着广泛的应用。由有源器件和电阻、电容构成的滤波器称为RC 有源滤波器。滤波器的分类很多，根据滤波器对信号频率选择通过的区域，可分为低通、高通、带通和带阻等四种滤波器；按使用的滤波元件不同，可分为LC 滤波器、RC 滤波器、RLC 滤波器；有源滤波器还分为一阶、二阶和高阶滤波器，阶数越高，滤波电路幅频特性过渡带内曲线越陡，形状越接近理想。
本实验设计了二阶RC 有源带通滤波器，并利用Multisim12.0 对实验进行仿真演示，列出了具体的分析与设计方法。
English abstract
The power filter is composed of capacitor, inductor and circuit filter circuit. The filter can be outside the power line frequency specific frequency or the frequency of frequency were effectively filter, a specific frequency power signal, or remove a specific frequency power 1signals. Filter in
communication technology, measurement technology, control systems and other fields have a wide range of applications. A filter called RC active filter, which is composed of an active device and a resistor and a capacitor. The classification of the filter, according to filter the signal frequency selection through a region can be divided into low pass, high pass, band pass and band stop and other four kinds of filter; according to the different use of the filter element can be divided into LC filters, RC filter and RLC filter; active power filter is first order, second order and higher order filter, the higher order, filter circuit amplitude frequency characteristic transition zone curve is steeper, the shape is more close to the ideal.
In this experiment, the two order RC active band pass filter is designed, and the Multisim12.0 is used to carry out the simulation demonstration, and the specific analysis and design method are listed.
