Abstract

PURPOSE:To ensure the high-quality panoramic display for the broadcast signal in a simple way, by carrying out the frequency sweep via the synthesizer. CONSTITUTION:The desired frequency is delivered from synthesizing circuit 12 in accordance with the frequency code of the fixed step sent from reception frequency control circuit 13. And thus the tuning point is decided between local oscillator 2 and high-frequency amplification circuit 1. The signal level supplied during the high-speed sweep is stored into memory circuit 14 via detection circuit 10. And the stored signal level is applied to display unit 11' to secure the accurate solid state display.
