I need help on a high order bandpass filter.
It is to be used with a vocoder. It needs to be high order so that the frequency drop off at the bandpass cut of point has a very large slope. we have to be able to fit 8 ranges within 100-1000 Hz. And to do this efectivly the passband region of each filter should not overlap eachother.

I was thinking a dualopamp with a bunch of capacitors?? i just need help with a basic layout for 1 filter, and the numerical computation for each band will easily follow.

Basicly we are building a 8 Band Vocoder and im thining of range of 200-1200??? Basicly just a normal male voice at normal speech??
