Can anyone help me locate a source for the equations that apply to Butterworth, Chebyschev, etc. filters? Specifically, I'm attempting to correlate the performance that I'm seeing out of an IIR Chebyschev bandpass implemented in software (National Instruments CVI)with a switched capacitor 6 pole unit that USED to be available from EG&G. Since they've obsoleted the part (RM5604), and since we've got a computer in the system, we've decided to go digital. Any help is appreciated.
