Hi Shehryar, The choice of N is mainly driven by the frequency resolution needed, which sets a lower boundary. N also is chosen so that (k/N)fs most accurately coincides with the actual DTMF frequencies assuming k are integer values and fs is a sampling frequency of 8 ks

I am designing an audio equalizer in Matlab, and I want to do it with a multirate setup, but I do not want to sample the input wave more than once, so if I have a sampling of say 50khz, I was wondering what the best way to decimate the signal would be in order to make it work.  I plan on implementing th
