Abstract

The invention consists of a method for bitrate transformation of digital signals in digital transmission systems in which additional bits are inserted in the digital signal before transmission at the transmitter and then removed again at the receiver. For this purpose a clock pulse is to be generated for writing into and reading out from a memory with address counters, and there must be no systematic pulse jitter. For this purpose the invention provides that on the transmitter side, the clock oscillator for the read-out pulse is phase-locked to a value m/n times the frequency of the clock pulse for writing into the relevant address counter. On the receiver side, the clock oscillator for the read-out clock pulse is phase-locked to a value n/m times the frequency of the write clock pulse. <IMAGE>
