Example of Designing a Chebyshev Digital High-Pass Filter Using MATLAB
First, determine the passband cutoff frequency and the stopband cutoff frequency of the Chebyshev high-pass digital filter. Call cheb1ord(), cheb1ap(), zp2tf(), lp2hp(), and bilinear() to obtain the low-pass digital filter model. Use freqz() to view the filter’s amplitude-frequency characteristics and lsim() to observe the signal filtering effect. %%qiebixuefu gaotong shuzi lvboqi sheji%%cheb1ord();cheb1ap();zp2tf();lp2hp();%%freqs();bilinear();freqz();lsim();%%%%%%%%%%%clear allclose all;clc;%%%%%%%%%%%%%%%Sampling frequency … Read more
