Abstract

PURPOSE: To enable the voltage set with high accuracy and to display preset operation, by presetting the tuning voltage with digital signal, in the channel selection unit of electronic tuning unit.
CONSTITUTION: In the channel selector providing the electronic tuner having the local oscillator of voltage control type and the preset means tuning with the channel desired by changing the voltage fed to the tuner, the electronic tuner circuit 1, DA converter 2, counter 3 changing the digital signal inputted to the converter 2, and preset control circuit 4 controlling the counter 3 with the preset operation are provided. Further, the preset display unit is constituted by providing the flicker signal generating circuit 5 operated with the control circuit 4, decorder 6 decoding the number of several bits at the higher rank of the counter 3, and the display element 7 displaying the tuning. Further, a signal is fed from the control circuit 4 to the signal generating circuit 5, the decorder 6 is controlled by generating flicker signal from the circuit 5, displaying the performance of preset operation to the display element 7
