Hello list, I realize that this may be a very elementary problem, but I'm new to DSP and would very much appreciate your help. If you are given a frequency response and you know that: 1. the part of the curve you're interested in can be modeled using a narrow bandpass IIR filter 2. you want to flatten that part of the curve how would you design the inverse filter? Also, how would you achieve the desired flat response? Thanks in advance, Rob

I'm extremely sorry for the 4 redundant posts. Google groups gave me 4 server time out messages and my post was accepted on the fifth try. I had no idea that the 4 earlier messages would show up. Sorry!

I suggest that you might want to looking into getting direct access to usenet. Maybe ask you ISP how to do this.
