段とを設けた受信装置。In a receiving device comprising a voltage synthesizer type tuning circuit and a tuner circuit whose local oscillation frequency is variably controlled by a tuning voltage signal of the tuning circuit, a received intermediate frequency signal output from the tuner circuit is amplified. an intermediate frequency amplification circuit that outputs an automatic fine adjustment signal by comparing the received intermediate frequency signal and a reference intermediate frequency signal using a built-in automatic fine adjustment circuit; an analog/digital conversion circuit that converts the signal into an N-bit digital signal and outputs it to the tuning circuit; a holding means for holding the digital signal; and correcting the tuning voltage signal based on the digital signal of the holding means and the digital signal of the conversion circuit during the reception period after the tuning operation, and adjusting the local oscillation frequency to the desired one. A receiving device equipped with a control means for controlling the frequency at a selected station.
