Parameters

  • cutoff_freq (float) – cutoff frequency of the filter

  • numtaps (int) – filter length, must be odd

  • show_freq_response (bool) – if True, will generate plot of frequency response

  • show_impulse_response (bool) – if True, will generate plot of impulse response

Returns

filter coefficients

Return type
