Web21 Oct 2013 · For a Bessel filter, this is defined as the point at which the asymptotes of the response are the same as a Butterworth filter of the same order. 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.) For analog filters, Wn is an angular frequency (e.g. rad/s). dignity health tracy ca
