Web13 May 2024 · A moving average filter can be thought of as a type of low-pass filter that doesn't have any control over its bandwidth for a fixed number of taps. For a finite impulse response (FIR) filter, the output signal y [ n] is given in terms of the input signal x [ n] and the filter taps h [ n] : y [ k] = ∑ n = 0 N − 1 h [ n] x [ k − n].
