WebJan 14, 2024 · A notch filter is a narrow band, high Q, filter that can sweep across frequency ranges. They are useful for tracking down offending and reducing sounds. Sweeping through frequencies also makes a cool sound! Q, explained A common function on … WebAs the gain is reduced, the -3dB passband BW is also reduced giving an apparent increase in Q or filter shape factor. Q = f c / Δ f ( − 3 d B) To optimize this filter, you must choose realistic pass BWp (-3dB) and stop BWs (-30dB) for a given center frequency. Expecting more requires more stages or tweaking of R. Also note that:
