WebNov 20, 2024 · The general form for a 2nd order high-pass filter is ( K is the voltage gain): Ks2 s2 + 2ζω0s + ω2 0 = Ks2 s2 + ω0 Q s + ω2 0 Butterworth The next thing is to look up the constants for Butterworth filter. These are usually given for the case where ω = 1. There's a very simple solution process for it, but a typical Butterworth table will look like:
