PURPOSE:To attain multiplexing without pulse width fluctuation by detecting a state change of a prescribed signal among plural discrete signals and applying multiplexing to the said plural discrete signals in response to the detected value. CONSTITUTION:A prescribed signal among the plural signals D0-Dn, e.g., the highest frequency signal is inputted to a change detection circuit 3 in a multiplex communication equipment multiplexing the plural discrete signals D0-Dn and the change detection circuit 3 detects the leading/trailing of the signal. Then the change detection signal is fed to a multiplex circuit 1 as a multiplex clock signal. The multiplexing circuit 1 uses the change signal to apply multiplexing to the input signal D0-Dn. Further, a change signal from an external state change application circuit 3 is fed to the detection circuit 2 to apply initial start of multiplex processing. |
