Abstract

PURPOSE:To adjust the separation to the best automatically even with the detection characteristics to be changed, by the FM modulation with a signal obtained through the addition between the mutliplication signal of the frequency and subcarrier signal, and the frequncy signal. CONSTITUTION:An oscillator 7 producing frequencies other than audio frequency is provided, and this frequency signal is applied to a signal generator 8. A synthesis signal is outputted to a VCO2 by using a signal in synchronizing with the subcarrier signal of a reception signal obtained at a MPX demodulator 6. Based on this output, the oscillation frequency of the VCO2 is controlled for FM modulation. To detect the level of the frequency signal component included in the right channel output of the MPX demodulator 6, a synchronizing detector consisting of a multiplier 9 and a low-pass filter 10 is provided.
