发明名称 Playback apparatus
摘要 A playback apparatus for a recorded frequency modulated television signal includes a filter between the record carrier pick-up heads and the limiter-demodulator. The filter characteristics increase the ratio of the carrier signal frequency to the lower side band frequencies in response to a drop in carrier amplitude.
