Abstract
An electronic circuit having reverse scan tuning comprises an IC radio having the forward scan function, in which a VCO capacitor is connected in parallel to a series connected resistor and switch, and a second switch is connects an input to an IF limiter amplifier to either circuit ground or a voltage supply. The invention makes it convenient for a user to search for a radio station by not having to start a search for a lower band station at the lowest end of the frequency band. The user does not need to push reset button to return to the lowest frequency when the user wants to receive a station whose frequency is lower than the current station.
