Method and device of connection and separation of a numerical channel low flow relative to high flow digital channel of a transmission link.

摘要

Under this procedure, added to the broadcast signal S1 (t) of a digital channel low output TO S2 (T) of a channel NUMERICO high output by some means of overshooting or overlay (13) creating a SIGNAL cOMPOSITE SHAFT S (T) AND THE RECOVERING IN THE RECEIVING SIGNAL S2 (T) CHANNEL NUMERICO high output thanks to regeneration means (24) OPERATING ON cOMPOSITE SHAFT S (T) signal and SIGNAL S1 (T) CHANNEL NUMERICO TRANSMIT A low output thanks to subtraction means (25) between the composite signal DRIVE S (T) prefiltered by a first lowpass filter (31) and the regenerated signal S2 ( T) NUMERIC CHANNEL HIGH DEBIT previously filtered by a second low-pass filter (33).
