Abstract

PURPOSE:To prevent malfunction of a signal processing circuit just after application of power by generating a signal equivalent to the ON-state of a squelch output during the transient period after application of power. CONSTITUTION:A synthesizing circuit 3 outputs a squelch output to a signal processing section 4 in response to the result of detection of a radio wave line state detecting circuit 1. A power voltage delay circuit 2 indicates a period from just after application of power till the end of transient state to the said synthesizing circuit 3. The sysnthesizing circuit 3 outputs a signal equivalent to the squelch signal to the signal processing section 4 during the period by the command. Thus, since the period at the application of power till the end of transient state is set to the squelch-on state, the malfunction of the signal processing section 4 for this period is prevented.
