Abstract

PURPOSE:To enable to remarkably reduce the hardware and to decrease the error of count value, by count and process in timesharing manner, through the use of a set of counter memory circuit and comparison circuit for a number of pulse inputs. CONSTITUTION:IC1-IC5 are J-K flip flop circuit, and the output inverted every reception of pulse input to the clock terminal CP of IC1 is fed to IC2. On the other hand, the gate control signal input is fed to the input terminal of IC3 to hold the output of IC2,IC3 by shifting them to IC4,IC5 with hold pulse. The output of IC2 and IC4 and that of IC3 and IC5 are respectively in logical operation with the NOR circuits IC6 and IC7. Further, from this operation, the count of input pulse is made by judging the presence of pulse input, presence of gate control signal, and input state of gate control signal.
