Abstract

PURPOSE:To eliminate effectively the noise caused by switching the reception mode by generating the breaking control signals through the control signal generation circuit to break the breaking circuit. CONSTITUTION:Pilot signal detection circuit 8 detects the presence or absence of the hetero-broadcast pilot signal via the sound multiple signal. And switch circuit 5 gives switching between the main and secondary aural signals in accordance with the detection output of the pilot signal to send the aural signal to breaking circuit 11. Circuit 11 is installed in the transmission path in order to break the transmission of the aural signal, and subcarrier detection circuit 13 detects the presence or absence of the subcarrier signal contained in the multiple sound signal. And the breaking control signal is generated from control signal generation circuit 12 in the state under the detection output of circuit 8 exists and the detection output of circuit 13 does not each. Thus circuit 11 is broken. As a result, the noise caused by switching the reception mode can be eliminated effectively even though the answer delay for the detection may exists in the detection circuit of the pilot signal.
