Abstract

PURPOSE:To always secure the normal value for the intensity of the FM electric wave to either one antenna and thus keep a good receiving state, by adding the sound outputs supplied from plural numbers of demodulating means through an adder and then delivering the added output to the speaker. CONSTITUTION:The signal received through the 1st antenna 1 receives a high frequency amplification at the high frequency amplifying stage 2 and then mixed with the oscillation output supplied from the local oscillator 6 and by the mixing circuit 3. And the differential frequency is amplified by the intermediate frequency stage 4 and then turned into the aural signal after receiving a wave detection through the demodulating stage 5. In the same way, the signal received through the 2nd antenna 11 is turned into the sound signal through the higher harmonic amplifying stage 12, the mixing circuit 13, the intermediate frequency amplifying stage 14 and the demodulating means 15 each. In this case, the oscillator 6 is shared by the 1st and 2nd demodulating means 5 and 15 are added together at the adder 7 and sent through the voice amplifying circuit 8 to drive the speaker 9.
