Abstract:
A plethysmographic or other signal is autocorrelated to give a first-pass determination of the distances among individual waveforms. A waveform is isolated, tested to determine whether its amplitude remains in suitable bounds for signal averaging, and convolved with the signal to match it with the other waveforms for averaging. Thus, a separate gating signal is not needed for signal averaging.
