Abstract
A method of recovering an original digital signal, after pulse stuffing, with reduced waiting time jitter. The original digital signal is written into a first elastic memory in a synchronizer. A pulse stuffed output of the synchronizer is transmitted to a desynchronizer where bits of the original signal are written into second elastic memory. Average values of fill levels of elastic memories in a synchronizer and in a desynchronizer are determined. The average value determined in the synchronizer is transmitted to the desynchronizer where a comparison of the respective average values is made in a comparator. A clock signal generating circuit in a phase locked loop is controlled by an output signal of the comparator so as to generate a clock signal. The signal bits written into the second elastic memory are read out of the second elastic memory at the rate of the generated clock signal.
