Abstract
PURPOSE: To facilitate an easy channel selection for the channel selector device by providing the tuning device.
CONSTITUTION: With selective operation of either one of memory/channel selection switches 1, the encoding is performed through encoding means 2 to be memorized in the memory provided at D-A converter 3. The memorized information is read out through switch 1 and then supplied to the tuner connected to terminal 53 via buffer amplifier 6, DC amplifier 7 and integrating circuit 8 respectively after the tuning voltage is selected through converter 3. Thus, the desired channel is selected. Control circuit 57 controls the up-down counter of converter 3 via switch 37 and 38, and thus the duty cycle is varied to genetate the sweep voltage. Then the sweeping is stopped at the tuning point.
