For a causal discrete-time FIR filter of order N, each value of the output sequence is a weighted sum of the most recent input values: $${\displaystyle {\begin{aligned}y[n]&=b_{0}x[n]+b_{1}x[n-1]+\cdots +b_{N}x[n-N]\\&=\sum _{i=0}^{N}b_{i}\cdot x[n-i],\end{aligned}}}$$ where: $${\textstyle … See more In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time. This is in contrast to See more An FIR filter has a number of useful properties which sometimes make it preferable to an infinite impulse response (IIR) filter. FIR filters: See more An FIR filter is designed by finding the coefficients and filter order that meet certain specifications, which can be in the time domain (e.g. a matched filter) and/or the frequency … See more • Electronic filter • Filter (signal processing) • Infinite impulse response (IIR) filter See more The filter's effect on the sequence $${\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. It is sometimes called a boxcar filter, especially when followed by decimation.
