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 … WebOct 4, 2024 · Ones & Zeros. While we are used to thinking of the effects of filters in the frequency domain, an FIR filter can be thought of as the time-domain (impulse response) representation of the same response. An FIR filter is simply a list of numbers between -1 and 1 (“coefficients”).
