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: • Require no feedback. This means that any rounding errors are not compounded by summed iterations. … See more A moving average filter is a very simple FIR filter. It is sometimes called a boxcar filter, especially when followed by decimation.
