Let's say I have an IIR filter that is a notch type with a peak at -20db. How do I modify the coefficients of the filter so that the peak is at -10 db for example?
I know I can scale the denominator coefficients so that the global peak amplitude can be set, but it affects the whole filter, which I don't want.
Here is what I want :
None
then there is no answer. $\endgroup$ – Dilip Sarwate Oct 14 '13 at 21:01
