<p>An electronic tuning radio receiver adapted to execute digital channel selection is provided with a circuit for detecting the deviation of a receiving frequency out of a band and a circuit for returning the receiving frequency into the band according to the output of the above circuit. These circuits can remove the disadvantages that the receiving frequency is further shifted below the lower limit of the band in band change-over. A multiplexer for effecting switching between each of channel selection systems is connected at its strobe terminal with a pulse generation circuit, which properly adjusts the channel selection speed.</p> |
