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. WebThe simplest low pass FIR filter you can try is y (n) = x (n) + x (n-1). You can implement this quite easily in VHDL. Below is a very simple block diagram of the hardware you want to implement.

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.
