RECEPTION CIRCUIT COMPONENT AND FRONT END SECTION OF RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a receiver adopting reception circuit components by which an audio signal is clearly received even when no video image is displayed because of a weak electric field strength signal and which is not vulnerable to the effect of an external signal and to allow a video signal from hardly being affected by harmonics produced from a local oscillation circuit. ;SOLUTION: The component is configured by containing a tuner circuit 2 that extracts a video intermediate frequency signal and an audio intermediate frequency signal of a selected channel from a signal received by a reception antenna 3, a high frequency amplifier circuit 4, a filter circuit 6 that passes only the video intermediate frequency signal, a filter circuit 7 that passes only the audio intermediate frequency signal, and a video intermediate frequency amplifier circuit 8 that amplifies the video intermediate frequency signal passing through the filter circuit 6 into a metallic case 10 and integrated therein.;COPYRIGHT: (C)1998,JPO
