Abstract

PURPOSE: To make it possible to perform continuously the channel selection of broadcasts different in frequency band and obtain a high reliability in a simple circuit constitution by operating practically one potentiometer.
CONSTITUTION: Tuning voltage supply terminals Bt of VHF tuner 9 and UHF tuner 36 in the electronic tuning system are connected to sliding element 17 of potentiometer 13 and voltage input terminal 35 of receiving band switching circuit part 34. In circuit 34, the input voltage of terminal 35 and the input voltage from intermediate tap 14 of potentiometer 13 are supplied to discriminator 20, and switching circuits 21, 24, 27 and 29 are controlled according to the difference between them, thereby performing the switching among a high band of VHF, a low band of VHF and a UHF band. As a result, the channel selection for each band can be performed continuously according to the position of sliding element 17.
