Scipy gaussian filter example
Web8 Aug 2014 · In gaussian_filter1d, the width of the filter is determined implicitly by the values of sigma and truncate. In effect, the width w is w = 2*int (truncate*sigma + 0.5) + 1 So (w - … 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).
