AbstractA digital filter for obtaining the power of a filtered signal passing through a particular frequency band for each frame (short time division) includes an auto-correlation circuit for calculating the auto-correlation function of the input signal, and a sum of products calculator for obtaining the power of the signal by multiplying a linear coefficient with the auto-correlation function for the frame and summing the products together to get the power of the filtered signal.
