Abstract

PURPOSE:To receive the audio multiplex broadcast excellent and without inconvenience, by providing the circuit which adds the opposite phase component of the main channel signal to the sub-channel signal and the opposite phase component of the sub-channel signal to the main channel signal. CONSTITUTION:The stereo widening circuit means 17, 18 consist of the buffer amplifiers 19A, 19B in common use for phase shifters, resistors RA, RB, capacitors CA, CB, and series connection system or stereo wide switches SA, SB. Further, when the reception state is in dubbing interpretation, the detection circuit 20 detects it, the switches SA, SB to turn on the muting transistors QA, QB are closed, but the signal from the amplifiers 19A, 19B of the means 17, 18 is grounded and it is not superimposed on another channel. On the other hand, in case of stereo state, since the circuit 20 does not turn on QA, QB but keep the off-state, the stereo wide function can be obtained with the operation of the switches SA, SB.
