摘　　要：研究低通、高通、带通、带阻这4种常用滤波器的工作原理。利用Multisim仿真平台设计出相应低通、带通滤波器;加入噪声后,利用示波器分别观察正常信号、噪声信号和滤波器输出信号,根据波形及参数进行滤波效果分析。This paper researches the working principle of four kinds of common filters, such as low pass, high pass, band pass, band stop filter circuit. At the same time, based on Muhisim simulation platform, the corresponding low - pass, band - pass filters were designed. By adding the noise to the circuit, we can observe the normal signal, noise signal and the filter output signal by oscilloscope. Finally, filtering effect was analyzed according to the wave- form and parameters.
