Witrynasignal.lfilter is designed to filter one-dimensional data. It can take a two-dimensional array (or, in general, an n-dimensional array) and filter the data in any given axis. It can also be used for IIR filters, so in our case, we'll pass in [1.0] for the denominator coefficients. In python, this looks like: y = lfilter (b, [1.0], x) Witryna30 sty 2013 · 0. I think the correct response is to generate the desire impulse response. For a raised cosine filter the function is. h (n) = (sinc (n/T)*cos (pi * alpha* n /T)) / (1 …
