3.3.1 Synchronized averaging
Problem
• Propose a time-domain technique to remove random noise given the possibility of acquiring multiple realizations of the signal or event of interest
Solution
• Linear filters fail to perform when the signal and noise spectra overlap.
• Synchronized signal averaging can separate a repetitive signal from noise without distorting the signal
• ECG signals may be filtered by detecting the QRS complexes and using their positions to align the waveforms for synchronized averaging

For synchronized averaging of order M
The resultant signal has a mean close to x
and a variance equal to
(a standard deviation equal to
Advantage
No spectral content of the signal is lost !
