ABSTRACT:
A channel selector comprising a tuning circuit including a variable reactance element as a tuning element and a non-volatile memory for permanently memorizing coded signals of channel selecting voltages to be applied to said variable reactance element, and being arranged in such a manner that the channel identification numbers and the coded signals for selecting these channels can be correspondingly memorized preliminarily in said non-volatile memory, and in channel selection the coded signal of the channel selecting voltage corresponding to a desired channel can be read out from said non-volatile memory, converted into a voltage and applied to said variable reactance element to achieve channel selection. A selected channel does not change by the cutting of the power source and the device is purely electronic. The device is especially effective for use in a television receiver.
