Nettet9. jun. 2024 · Moving Average in its general form is basically an FIR Filter which means it can mimic any linear system you'd like by the choice of the length and coefficients. If you mean Moving Average by a filter of length $ N $ and with coefficients of the form $ \frac{1}{N} $ then this constant sliding window will have LPF effect indeed.
NettetIn the case of moving maximum, moving minimum, and median filter objects and blocks, you can not specify the overlap length. The algorithm assumes the overlap length to be window length – 1.
