<p>PURPOSE:To process and control digital signals effectively by generating a synchronizing signal, following up cycles of an input signal proportionally at a fixed position in one cycle of the input signal by generating a coincidence signal by comparing the output of a voltage-dividing circuit with that of a memory circuit. CONSTITUTION:Integrating circuit 2 converts an input signal into a saw-tooth wave by integrating each period, the maximum of the output of circuit 2 is stored 3 at every time of the synchronization of the circuit output and voltage-dividing circuit 4 voltage-divides the output of circuit 3 by a predetermined rate and geneates an output. Here, the output of circuit 4 is compared 5 to that of circuit 3 and when the both agree with each other, a coincidence output is generated. At a fixed position in one cycle of the input signal, a synchronizing signal is generated which follows up the period of the input signal proportionally. Consequently, the processing of, control over, etc., digital signals such as the generation of a timing signal at a random position in one period can effectively be performed.</p> |
