Abstract
An electronic tuning radio receiver for executing digital channel selection is provided with a circuit means (b.sub.9) for detecting that a receiving frequency is out of the band and circuits (60, 62, 48, 50) for returning the receiving frequency within the band by the output of the above circuit means. Disadvantages that the receiving frequency is further driven below the lower limit of the band in the band switching can be avoided by these circuits. Pulse generator circuits (144, 142) are connected for the strobe terminals (G) of the multiplexer (46) switching various types of channel selection systems to moderate the channel selection speed by these circuits.
