Abstract

PURPOSE:To improve the quality of audio signals in case of mjltiplex broadcast, by processing the output of a tuner of a TV receiver at an audio reception circuit having a specific selectivity, so that the video carrier wave signal and the audio carrier wave signal can only have small difference. CONSTITUTION:Video and audio intermediate signal PS are branched into two from a tuner 1 of a TV receiver, and one signal PS1 is processed at a video reception circuit 2. Further, another signal PS2 is inputted to an audio reception circuit 20 and fed to a band pass filter 21 of a reception circuit 20, and from the frequency characteristic of this filter, the deviation between the level of the audio carrier wave signal and that of the video carrier wave signal is made less for the pickup. The picked up video, audio carrier wave signals are inputted to a video intermediate frequency amplifying circuit 22, synchronizing detection is made by using a video detection circuit 23, and the audio signal component to the video signal component of the detected output signal is made greater, and the audio signal A with excellent quality can be output to the output of an audio amplifier circuit SIF 25 via an audio intermediate wave SIF filter 24.
