Date Aug. 30, 1984.In transmission of PCM signals resulting from sampling and quantizing analog signals, the PCM signals are modulated according to a desired rule of modulation and a synchronizing interval is provided for every given interval of time, the synchronizing interval being longer than a level change interval as determined by the modulation rule. The synchronizing interval is followed by a level reversal interval which is approximately equal to the longest level change interval as determined by the modulation rule.
