Hi
I am designing a graphic equalizer for ISO frequency starting from 31.5 Hz 63Hz ... 16000Hz
I decided to use a 48000Hz as a sampling frequency. In Short for graphics equalizer if my slider position is on 0dB I should pass the signal as is.
Problem is when I design a filter for [ 31.1, 63, 125, 250, 500] @ 48KHz poles of the filters are very close to unit circle and can affect each other. Really not good numbers!
I used peak filter design from mat lab filter design toolbox.
So I want to design a good transfer functions so that I can get good pole zero plot at these lower frequency. And will be happy is somebody pour good valid thoughts on this problem.
"In Short how to design transfer function for peaking filter hows pole zeros are good"!
