WebThis cookbook recipe demonstrates the use of scipy.signal.butter to create a bandpass Butterworth filter.scipy.signal.freqz is used to compute the frequency response, and scipy.signal.lfilter is used to apply the filter to a signal. (This code was originally given in an answer to a question at stackoverflow.com.) WebAmong the Gaussian, Hamming (Bres et al., 2003), Legendre, Tchebyscheff or Wiener filters (Jain, 1989), the Butterworth filter (Bres et al., 2003;Labarrère et al., 1993) is one of the filter ...
