Abstract: The synchronization method realizes synchronization of a digital input data signal with a digital clock signal with which the data signal is rate synchronous. The method consists in sampling the input signal, grouping these samples in successive sets of a plurality of successive ones of the samples, detecting in each of the sets possible value transitions of the samples, determining for each current transition in a set the theoretical position thereof in a corresponding set assumed to be obtained by sampling a nominal data signal which is the input data signal but with pulses having a width equal to the width of the clock signal period, and using the latter theoretical position and the end value of the transition to generate the synchronized input data signal.
