Abstract
A digital signal transmission system operates in a mode for transmitting multiplexed signals as a serial digital signal and in a mode for transmitting only a predetermined signal. A transmitter of the system includes a first control circuit which, in a particular signal transmission mode, places only a particular signal processing circuit block for transmitting a particular signal in an operative state and places in an inoperative state a multiplexer circuit block for multiplexing the predetermined signal with at least one other signal. In a multiplexed transmission mode, the first control circuit places in an operative state only the multiplexer circuit block and places in an inoperative state the particular signal processing circuit block. A receiver of the system includes a second control circuit which, in a particular signal transmission mode, places a particular signal restoring circuit block for restoring the transmission signal received through the transmission path to an operative state and places in an inoperative state a demultiplexer circuit block. In an multiplexed transmission mode, the second control circuit places in an operative state only the demultiplexer circuit block, which demultiplexes a multiplex signal received through the transmission path into a plurality of digital signals, and places into an inoperative state a particular digital signal restoring circuit block.
