Abstract: This invention relates to an automatic tuning method and apparatus in which tuning voltage corresponding to picture/sound carrier wave difference of channel selected by double conversion tuner is transmitted to voltage control oscillator to thereby be re-tuned so that input filter inseting loss according to said picture/sound carrier wave is minimized, which is characterized by comprising automatic tuning device comprising, phase locked loop PLL circuit for controlling oscillation signal of local oscillator of tuning circuit, video intermediate frequency VIF producing circuit which receives output signal of said tuning circuit whereby outputting RF automatic gain control AGC signal and IF automatic gain control signal, and automatic tuning means which receives two output signals from said video intermediate frequency producing circuit whereby controlling band pass filter signal of the tuning circuit.
