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.) WebNotes. The Butterworth filter has maximally flat frequency response in the passband. The 'sos' output parameter was added in 0.16.0.. If the transfer function form [b, a] is requested, numerical problems can occur since the …
