Abstract

Noise impulses are suppressed in a signal processing circuit by gating an input signal. The gated signal is then smoothed upstream of demodulating the smoothed signal as viewed in a signal flow direction from a signal input to a processed signal output. The signal processing circuit system includes at least a signal gating section followed by a signal smoothing section followed by a demodulating section in that order and as viewed in the signal flow direction. Thus, smoothing takes place prior to demodulation.
