Abstract

PURPOSE:To enable excellent audio multiplex reception, by avoiding the input frequency of audio carrier to the frequency discriminator from being affected with the local oscillation frequency of TV tuner, in the separation carrier system TV audio multiplex receiver. CONSTITUTION:The TV turner consists of the high frequency amplifier 1, first mixer 2, and first local oscillator 3, and the audio intermediate frequency is fed to the amplifier 6 from the mixer 2, the output is mixed with the output of the second local oscillator 9 at the second mixer 10 and it is outputted to the audio output unit 14 via the frequency discriminator 12 and multiplex demodulator 13. The output of the amplifier 6 is in frequency conversion with the search tuning systems 9-12, 15-17 at the sweep output signal of the local oscillator 9, and when the sweep second audio intermediate frequency signal reaches the specific frequency specified, the sweep is stopped, and feedback control is made so that the input signal frequency to the frequency discriminator 12 can be equal to the specific frequency, and the input frequency to the discriminator 12 is not affected with the change in the local oscillation frequency of the tuner.
