Signal averaging by parallel digital filters
Cecil W. Thomas, M. Rzeszotarski, Barry S. Isenstein · IEEE Transactions on Acoustics Speech and Signal Processing · 1982
Signal averaging for signal-to-noise ratio improvement is modified by using parallel digital filters instead of the classical block averager. The digital filter averager allows the user to specify the signal-to-noise ratio improvement, and it computes a continuously updated average. The steady-state and transient performance of the averagers are demonstrated by equations and by simulation.
