高通滤波器分析及其仿真

摘要

The experimental module of high-pass filter on the THKSS-D Signals and Systems experiment case is analyzed with the s-plane geometry analysis technique, the amplitude frequency characteristic and phase frequency characteristic are given , cut-off frequency is also obtained , and high-pass active filter and passive filter both with equal RC parameters is compared with and simulated with Matlab.%分析了THKSS-D型信号与系统实验箱的高通滤波器实验模块,用S平面分析法给出其幅频特性和相频特性,根据通频带定义给出该滤波器截止频率,对有源和无源高通滤波器进行比较,并用Matlab软件对其频率特性进行仿真.
