[net.audio] Filter design info wanted

karn (05/11/83)

I'm looking for cookbook references that would help me design a Bessel
low-pass filter using switched-capacitor chip(s).  (A Bessel filter has
maximally flat phase response across the passband.)

This is for a data demodulator, not an audio application, but I figured
that those with the expertise would most likely be on this newsgroup.

Thanks,
Phil Karn
