Spectral and Synchronous Averaging

 Specifically, learn how to combine running, exponential, sliding, and weighted moving averages in unique ways that lead to novel averaging approaches such as the triple exponent moving average and the Hull moving average. You’ll also see how these same averaging techniques are applied in the frequency domain to power spectrums using the Simulink Spectrum Estimator and Spectrum Analyzer blocks.
