Abstract
PURPOSE: To ensure the normal actuation of the automatic frequency control function for every reception channel by adding the fixed circuit.
CONSTITUTION: The video intermediate frequency signal is applied to input terminal 5 of automatic frequency control signal generator circuit 1, and the output is caused at terminal 6 in accordance with the shift of the video intermediate frequency supplied. This output is converted into two signals featuring the polarity as it is and the opposite polarity each through converter circuit 7 to be connected to switch circuit 10. These converted signals are then controlled by the signal caused in accordance with the channel setting of channel selection device 3. Then the output of circuit 7 and featuring the different is drawn out selectively from switch circuit 10 to be supplied to tuner 11. Thus the automatic frequency control function is never impaired by the reception band.
