MULTIPLEXING APPARATUS HAVING BSI-CODE PROCESSING AND BIT INTERLEAVE FUNCTIONS

摘要

MULTIPLEXING APPARATUS HAVING BSI-CODE PROCESSINGAND BIT INTERLEAVE FUNCTIONSABSTRACT OF THE DISCLOSUREA multiplexing apparatus of a bit interleave typefor time-division multiplex on PCM signals of a plural-ity of channels bit by bit to convert the PCM signalsinto a high-speed PCM signal. To maintain the advantageof the synchronous multiplex system, the multiplexingapparatus has a BSI-code processing function and a bitinterleave function and comprises: a BSI-code addingcircuit for adding BSI codes to the PCM signals beforemultiplexing; a BSI-code position shifting means circuitfor shifting the positions of the BSI codes in the PCMsignals to different positions respectively with respectto the PCM signals of a plurality of channels; and amultiplexing circuit for multiplexing the outputs of theBSI-code position shifting circuit by a bit-interleavemode.
