Is there any way I could utilise
findpeaks in conjunction with
fvtool? I would like to know where on the frequency axis the maximum and minimum of my frequency response happens.
fvtool is interactive so it doesn't let you recover an data in a script. Fortunately you can use the
freqz function to get the same frequency response. Something like this might work:
[h,w] = freqz(b,a); % h is frequency response, w normalized frequency mag = 20*log10(abs(h)); [minval,minidx] = min(mag); minfreq = w(minidx); [maxval,maxidx] = max(mag); maxfreq = w(mcxidx);
