Abstract

PURPOSE: To fix one tuning indication point of a TV receiver of a continuously- variable tuner each for one broadcast station, by providing a 2nd video IF amplifier circuit whose band is narrower than that of a video IF amplifier circuit.
CONSTITUTION: An IF signal from tuner 1 is supplied to video IF amplifier circuit VIF1 by way of contact (a) of switch SW1 and then inputted to TV circuit 8. Further, the IF signal from tuner 1 is supplied to audio amplifier 7 through converter 5 and IF amplifier 6. Simultaneously, sound IF signal (s) from IF amplifier 6 is supplied to detection circuit 4. Here, the output of tuner 1 is inputted to 2nd VIF2 of narrow-band frequency characteristics with single-peak characteristics near a video IF carrier and its output (p) is inputted to detection circuit 4. Then, circuit 4 rectifies signals (s) and (p) to drive tuning indicator 9 on the basis of rectified values. Thus, the tuning indication of one point each for one broadcast station can be attained.
