Abstract
A station selector comprising a first memory for memorizing the first decimal digit of a given channel number in a form of a corresponding binary signal, a second memory for memorizing the second decimal place digit of the channel number in a form of corresponding binary signal, first and second binary-to-decimal converters for converting the contents of the first and second memories into corresponding decimal signals, a matrix circuit for combining the decimal outputs of both the first and second binary-to-decimal converters such that the resultant combination can be taken out from one of the intersections of a matrix corresponding to a given two-digit decimal channel number, and a preset voltage circuit having a plurality of preset channel selection voltage elements adapted to provide respective preset channel selection voltages and selecting one of the voltages for selecting a channel of a corresponding channel number in response to the output taken out from the afore-said intersection, the selected voltage being coupled to a variable reactance element in an electronic tuner section. With this system it is possible to readily preset desired channels.
