    Frequency Response of the Running Average Filter The frequency response of an LTI system is the DTFT of the impulse response, H(ω) = ∑ (m = − ∞ to ∞) h(m) e − jωm. The impulse response of an L-sample moving average is h(n) = 1/L, for n = 0, 1, ..., L − 1...

    Usage The moving average filter is used to remove noise from time series and other temporal data as well as for low-pass filtering. Despite it's simple nature, it can be useful for certain types of smoothing. For a more robust and preserving filter, use t...
