Abstract
PURPOSE: To eliminate erros owing to the pulse intervals of reference clock pulses by forming a circuit which outputs the square waves having the periods coninciding in time mode and having a fixed pulse width for the square wave input data of the frequency to be converted.
CONSTITUTION: When a square wave input 11 becomes 1 from 0, the reset signal 35 of a pulse counter 7 becomes 0 from 1 and the counter 7 assumes an operating state from a reset state. At this instant, the output 33 of an exclusive OR circuit 23 becomes 1 from 0 and a reference frequency generator 21 starts oscillating by means of a square wave input signal 11. The counter 7, inputted with clock pulses 31, starts counting and emits 1 to the counter output 32 at the instant when it counts by preset number. When the output 32 becomes 1, the another input 11 of the circuit 23 is also 1, and therefore the output 33 thereof becomes 0 from 1. At the same time the signal 34 for stopping oscillation function becomes 0 from 1 and the generator 21 stops oscillating.
