Abstract

PURPOSE:To adjust the delay time of an output to a constant value automatically independently of the load by providing a means discriminating a voltage or current level and a switch means turned on/off by a control signal from a gate. CONSTITUTION:In a level discrimination means 900, a voltage inputted through the branch of output is compared with a predetermined reference voltage and n-set of discrimination signals are outputted. A discrimination signal of an output of a level discrimination means 900 is given to one input of gates 50-1-50-n and a signal being the result of a branch of an input digital signal is fed to the other input, and a control signal depending on the input of the both is outputted. The control signal is fed to switch means 30-1-30-n to apply on/off operation and a digital signal processing circuit connected to the switch means turned on is in the operative state. As a result, the digital signal processing operated by the switch means is operated in parallel with a digital signal processing circuit 150-0, the output current is increased and the delay time of the output signal is set to a prescribed value.
