This is in contrast to See more An FIR filter has a number of useful properties which sometimes make it preferable to an infinite impulse response (IIR) filter. FIR filters: See more 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 … See more • Electronic filter • Filter (signal processing) • Infinite impulse response (IIR) filter See more The filter's effect on the sequence $${\displaystyle x[n]}$$ is described in the frequency domain by the convolution theorem: where operators $${\displaystyle {\mathcal {F}}}$$ See more A moving average filter is a very simple FIR filter.
