電子同調チューナ。In an electronic tuning tuner that generates a tuning voltage corresponding to each channel and applies the tuning voltage to a tuning circuit in a high-frequency amplifier circuit to vary the tuning frequency and receive a desired channel, each selection of adjacent channels is A correction voltage generating means for generating 2·K positive and negative correction voltages each having an absolute value of each voltage obtained by dividing a predetermined voltage sufficiently smaller than the difference in local voltage into K (K is a natural number) equal parts, and the correction voltage. an adder that adds each voltage to the channel selection voltage and applies the result to the tuning circuit; and a tuning instruction voltage that detects a reception state that changes according to each of the 2·K correction voltages and responds to the reception state. and a reception state detection circuit that extracts the tuning command voltage corresponding to each of the 2·K correction voltages, selects the optimal tuning command voltage that indicates the optimal reception state, and performs correction corresponding to the optimal tuning command voltage. An electronic tuning tuner comprising selection means for generating a voltage from the correction voltage generation means.
