MATLAB program for the design and implementation of Chebyshev band pass filter

Program code

%Chebyshev band pass filter

clc;

clear all;

close all;

fp1=input ('Please input the first pass band frequency = ');

fs1=input ('Please input the first stop band frequency = ');

fp2=input ('Please input the second pass band frequency = ');

fs2=input ('Please input the second stop band frequency = ');

rp=input ('Please input the pass band attenuation = ');

rs=input ('Please input the stop band attenuation = ');

sf=input ('Please input the sampling frequency = ');

p1=2*fp1/sf;

s1=2*fs1/sf;

p2=2*fp2/sf;

s2=2*fs2/sf;

p=[p1,p2];

s=[s1,s2];

[n,w]=cheb1ord(p,s,rp,rs);

[f1,f2]=cheby1(n,rp,w,'bandpass');

freqz(f1,f2);

title ('Chebyshev Band Pass Filter');

Example of output

Please input the first pass band frequency = 2000

Please input the first stop band frequency = 1600

Please input the second pass band frequency = 3000

Please input the second stop band frequency = 3200

Please input the pass band attenuation = 0.5

Please input the stop band attenuation = 50

Please input the sampling frequency = 9000
