WebJun 1, 2024 · 4th order filters are very common in audio related stuff, or for something like a PWM output filter. This circuit is perfect for a PWM filter, since the exact Q and Fs are not really critical. So if you just choice a Q around 0.5-0.6 that will be just fine (and always stable). Unity gain would only be easier. Logged http://www.oneworldconcepts.com/ WebMar 13, 2024 · To get higher order filters they are cascaded aka chained in series. Bellow is a single biquad section, 2nd order IIR filter, where $ Z^{-1} $ is a delay of 1 sample and b[N] are the coefficients for each Tap on the input side (feed-forward) and a[N] are the coefficients for each Tap on the output side (feed-back):
