Abstract
In order to restore a clock signal which has been used for coding signals transmitted on a transmission channel, the transition instants of these signals are precisely detected by analyzing a series of samples taken from the signals during at least one fraction of the clock period. A device first determines the deviations between the respective amplitudes of the various samples that have been taken. Comparison of the deviation configuration obtained with standard configurations that have been determined previously makes it possible to estimate the position of the time window where the sampling was achieved in relation to the analyzed period fraction and therefore to decide whether this window is correctly centered. If it is not, a local clock is phase shifted so as to have the time window resynchronized.
