WebJul 4, 2024 · 1. Your filter has a zero at z = − 1 and a pole at z = 0.939 so it can't be invertible. You can move the zeros slightly inside the unit circle such as z = − 0.95 and then the filter coefficients would be b = [0.0305, 0.0289] and a = [1.0000, -0.9391], which is also a low-pass filter but its attenuation at π is a little bit lower compared ... Web1. You are thinking of a solution that is inappropriate. Filtering a PWM signal requires only low pass filtering and not envelope detection and certainly not the 2nd circuit you have shown.
