摘要： In a channel selecting apparatus for a television receiver having an electronic tuning tuner for changing the receiving frequency in accordance with an analog control signal applied thereto; a memory has a plurality of addresses for storing respective digital codes each identifying a respective channel, and such addresses in the memory are selectively activated so as to effect read out of the respective channel identifying digital code to a digital-to-analog converter which converts the same into a respective analog control signal for the tuner. Deviation of the receiving frequency, as established in response to the analog control signal, from the correct receiving frequency for the channel identified by the digital code then being read out of the memory is detected, and in response to a detected deviation the ditial code being received by the digital-to-analog converter is automatically modified or changed in the sense for removing said deviation and thereby effecting a fine tuning operation. In a preferred embodiment, when the detected deviation of the established receiving frequency from the correct receiving frequency exceeds a predetermined amount, the resulting modified digital code is stored in the memory in place of the read out digital code resulting in such deviation, thereby to ensure that the stored digital codes will not, with time, result in respective receiving frequencies that are outside the pull-in range of the automatic fine-tuning operation.
