imp_urhp filter matlab code:
Code: [Select]
Fs = 96000;  % Sampling Frequency
Fstop = 21500;            % Stopband Frequency
Fpass = 21510;            % Passband Frequency
Dstop = 3.1622776602e-10;  % Stopband Attenuation
Dpass = 5.7564627261e-05;  % Passband Ripple
flag  = 'scale';          % Sampling Flag

[N,Wn,BETA,TYPE] = kaiserord([Fstop Fpass]/(Fs/2), [0 1], [Dpass Dstop]);
b  = fir1(N, Wn, TYPE, kaiser(N+1, BETA), flag);
