WebMay 11, 2014 · Wn : array_like. A scalar or length-2 sequence giving the critical frequencies. For a Butterworth filter, this is the point at which the gain drops to 1/sqrt (2) that of the passband (the “-3 dB point”). For digital filters, Wn is normalized from 0 to 1, where 1 is the Nyquist frequency, pi radians/sample. ( Wn is thus in half-cycles / sample.) WebMay 19, 2024 · A Butterworth filter is a type of signal processing filter designed to have a frequency response as flat as possible in the passband.
