Abstract: A method for synchronizing the receiver and the transmitter in a PCM-receiver system wherein binary information is transmitted within cyclically occurring channels. The last bit of each of the channels form a synchronization pattern, which is regular but has at least one irregularity which occurs within a predetermined channel. By first using the regular part of the synchronization pattern for synchronizing the bit distributors of the transmitter and the receiver and then the irregularity for synchronizing the channel distributors a very fast two stage synchronization process is obtained.
