WebFeb 16, 2024 · Let’s compute the third order Butterworth filter with 150 kHz pass-band and unity gain. For a 3rd order Butterworth filter K1 = K2 = 1, so ω1 and ω2 are equal to its radial pass-band frequency, and Q = 1. Choose the feedback R3 value, for example, 1 kOhm, and the R4 value, for example, 100 Ohm.
