Abstract

PURPOSE:To secure the effectiveness of the data even in the preset period by delivering the output when the subtractor counter has the count value of O and then giving the resetting by applying the output in the form of the reset signl of the FF. CONSTITUTION:Pulse generator 4 generates the continuous pulses, and output terminal 5a of pulse separator 5 delivers the pulses in the fixed number immediately after the control signals are applied from outside. And terminal 5b delivers the pulses generated from generator 4 after the output through terminal 5a. The output terminal of setting switch 7 is connected to subtractor circuit 8, and the set value is read in by the output given from terminal 5b to be counted down in sequence with every output pulse sent from terminal 5b. At the same time, counter 8 delivers the output when the count value becomes O and applies it as the reset signal of FF3 for resetting. In this way, the effectiveness of the data can be secured even in the preset period.
