SYNCHRONISING APPARATUS FOR A DIGITAL SIGNAL DEMULTIPLEXER

摘要

The object consists of equalising a bit slip during the demultiplexing of a multiplex signal. A bit-slip detection device (10) detects a bit slip and controls a clock frequency switching circuit (11) in such a manner that the number of the bits output to the outputs (4a-4d) of the demultiplexer (3) is returned to the nominal value by accelerating or decelerating the clock at the main frame counter (8). The invention is used in digital signal demultiplexers.
