WebApr 11, 2016 · Two possibilities I can think of: 1. Incorporate your feedforward as a gain, i.e. instead of having y = u + a*y, write y = u/ (1-a). This is the exact solution. 2. As a quick fix, you can include a memory or delay element. This shifts everything by one time step though. I think it's still possible. 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…
