Abstract
PURPOSE: To prevent the malfunction of AFT in respect to sound IF signals by correcting the AFT voltage by detection signals of video signals.
CONSTITUTION: Contents of counter 13 are set to a value corresponding to the receiving frequency on a basis of the receiving operation, and this value is D/A- converted by converter 18 to form a channel selection voltage. Then, the channel selection voltage is supplied to electronic tuning-type tuner 1, and the frequency designated by the receiving operation is received. In this case, the value of counter 13 is corrected by the AFT voltage, thereby performing AFT; and meanwhile, the presence of video signals is detected, and the AFT voltage is corrected by this detection signal. As a result, the malfunction of AFT can be prevented in respect to sound IF signals
