Abstract

PURPOSE: To select the series resonance circuit trapping the adjacent broadcast channel signal when television signals such as independent broadcast are transmitted to the adjacent channel of normal broadcast channel, at the same time with the channel selection of the television receiver.
CONSTITUTION: The independent broadcast television signal is converted into the second and 5th channel and fed to the terminal 12, and it is fed to the antenna terminal 29 of the receiver 11, via the brancher 27. On the transmission line between the terminal 12 and the brancher 27, the series resonant circuits 17, 20, 23 and 26 trapping the signal of the 2, 5, 1, and 4th channel of television signal are connected via the switches 13 and 14, which are controlled with the circuit including the relays 36 and 41 detecting the leakage signal from the local oscillator 31 changing the outgoing frequency with the channel selection of the tuner of the television receiver 11.
