An FIR filter is designed by finding the coefficients and filter order that meet certain specifications, which can be in the time domain (e.g. a matched filter) and/or the frequency domain (most common). Matched filters perform a cross-correlation between the input signal and a known pulse shape. The FIR convolution is a cross-correlation between the input signal and a time-reversed copy of the impulse response. Therefore, the matched filter's impulse response is "designed" b… WebJul 27, 2016 · KVR Audio Forum - Designing a FIR lowpass filter in C++ (calculating coefficients?) - DSP and Plugin Development Forum
