Abstract

PURPOSE: To make easy circuit integration, by unifying the input system for each instruction signal such as sweep inhibit signal and compulsive inhibit signal, by using a pulse generator and two input OR circuit.
CONSTITUTION: Between the terminal 17 of the reception circuit 1 outputting the two states of logic 1 and 0 depending on the presence of input signal and the second input terminal 45 of the control circuit 40, the pulse generator circuit 41 and the OR circuit 42 are connected. When the compulsive inhibit signal is fed to the terminal 49, the sweep start signal inputted to the first input terminal 44 of the circuit 40 is not received. But, if this applied signal is absent, the sweep start signal outputs the oscillation frequency information from the output terminal 43 of the circuit 40 to sweep the circuit 1. When the input signal enabling reception during sweep is detected, pulses are generated in the circuit 41 via the terminal 17, and this signal is inputted as the sweep inhibit signal via the circuit 42. Thus, the input system can be unified and accordingly, the number of terminals for the circuit 40 is less to enable circuit integration easily.
