Abstract
The invention discloses an electronic channel selector which comprises a plurality of variable resistors, a plurality of switches connected to the variable resistors, respectively, and a voltage memory circuit. When one of the switches is closed, the output voltage of the variable resistor corresponding to the closed switch is transferred into and stored in the voltage memory circuit, and in response to the output voltage from the memory circuit the capacitance of a varactor may be varied for selecting a desired channel. The electronic channel selector in accordance with the present invention may be used instead of the conventional mechanical tuners, the channel selection may be much facilitated, the defects encountered in the conventional electronic channel selectors may be overcome, and any desired channel may be stored.
