摘要: A television tuning system includes UHF and VHF signal paths each tuned by a voltage coupled to common path diplexer. So that signals will be attenuated so not cause interferences with channel which is selected viewed, the filter detuned when selected. Detuning accomplished modifying for responsive band-switching voltage.
