The audio output circuit control section 7 controls the signal power of the audio output circuit 8A that follows.
いま、目的周波数搬送波が他の機器により送信

Therefore, the subsequent stage circuit is supplied with power and has the output of the second squelch circuit 4 which operates by detecting the desired signal in the target frequency carrier wave. If the desired signal is present in the demodulated signal, the secondary squelch circuit 4 stops the operation of the timer circuit 5 and maintains the switching circuit 6 controlled by its output in a conductive state.

れ、同率で消費電力も低減される。 In addition, when the desired signal does not exist in the target frequency carrier wave, the primary squelch circuit 3 detects the carrier wave and enables the subsequent stage to operate, but since the secondary squelch circuit 4 is in a no-input state, the timer circuit Therefore, the timer circuit 5 outputs a built-in continuous pulse with a constant period, turns off the switching circuit 6 at the same period, and controls the secondary squelch circuit 4 and the audio output circuit control section 7. power on and off. At this time, the audio output circuit 8A is subordinate to the audio output circuit control section 7, and no power is consumed when the power is cut off. Further, by setting the built-in period of the timer circuit 5, the time rate of power supply to the secondary squelch circuit 4 and the audio output circuit control circuit 7 is set, and the power consumption is also reduced at the same rate.
