Thread: Biquad Filter Transfer Function

  1. #1

    Biquad Filter Transfer Function

    I would like to know if there is documentation on the transfer functions used specifically for the band-pass and band-stop (notch) filters?

    The source code for those filters in the audio library on your system is found in filter_biquad.cpp and filter_biquad.h.

    The comments in those files say

    // Compute common filter functions

    so I would refer to the above link for the nasty details.

    Thank you I had seen it before but I had forgotten where it was and I couldn't find it again. These are the nasty details I was looking for.

    Thank you
