Abstract

PURPOSE:To multiplex a transmission line in time division to make transmission possible with one transmission line only by providing a time prescribing circuit, which performs a simple logical operation for time-prescribed parallel signals, before or after a parallel-series converter. CONSTITUTION:Parallel signals A and B inputted to interface circuit 1 are converted to series signals by multiplex transmission circuit 2 and are transmitted by transmission cable 7 and are demodulated by demodulator circuit 4 and are converted to parallel signals. However, in case that the minimum time difference to be satisfied between signals A and B is T1, outputs of the same timing are issued as demodulation outputs because the time difference is eliminated at a sampling time of multiplexing, and therefore, a time-prescribed parallel output are obtained as the output of time prescribing circuit 10 by delaying input B by time TD(>=T1) for input A by time prescribing circuit 10 in case of the same timing of inputs A and B. The time prescribing circuit is constituted by the waveform operation circuit of delay lines, etc., provided between respective outputs and inputs.
