Abstract
This method which enables two periodic signals having the same waveform and the same theoretical period to be synchronized is of the type in which the second signal is synthesized iteratively at a phase that is adjusted as a function of a measure of the correlation between the first and second signals. Synchronization is obtained by progressively shifting the phase of the second signal until a correlation maximum is detected, after which said signal is locked onto the correlation peak by phase skips on either side thereof.
