    • A digital signal multiplexer of this invention comprises n (an arbitrary integer) multiplexing circuits (11 to 1n) that converts signals input from a plurality of circuits into m (an arbitrary integer) parallel signals having a first transmission speed to which an additional bit is added, a parallel-serial converter circuit (40) which converts m parallel signals sent from n multiplexing circuits into multiplexed signals of the serial form, and buses (30) that connect n multiplexing circuits and the parallel-serial convert circuit together. Each of the n multiplexing circuits has a circuit that successively sends the m parallel signals onto the buses using pulse signals of a second transmission speed which is n times as fast as the first transmission speed. A digital signal separator of the invention comprises a serial-parallel converter circuit (75) for converting the serial input signals into m (an arbitrary integer) parallel signals having a predetermined speed, n (an arbitrary integer) separating circuits (51 to 5n) that separate the additional bit from the m parallel signals of the serial-parallel converter circuit (75) and send the signals onto a plurality of circuits at the above predetermined speed, and buses that connect the serial-parallel converter circuit (75) and the n separating circuits together. Each of the n separating circuits has means for receiving signals from the serial-parallel converter circuit sent onto the buses at a clock timing of the same speed as the predetermined transmission speed.
