Abstract

PURPOSE:To realize the display of channel number with a simple circuit constitution, by registering and storing the channel number. CONSTITUTION:At the preset of tuning voltage, digital value 2 is determined with a control circui 1, and this is stored in the digital tuning voltage memory 3. The storage number is determined with the address signal group 5 being the output of the channel selection circuit 4. The signal group 5 is connected to the channel number memory 6 in this case and this corresponding storage number is accessed. When the storage to the memory 3 is finished, the channel number input unit 7 is operated and the preset channel number is registrated in the corresponding storage address of the memory 6. Next, at the usage of channel selection unit, address signal is generated from the channel selection circuit 4 to select the data in the memory 3 and it is fed to the tuner 10 via a D/A converter 8, and low pass filter 9. In this case, the channel number data is displayed on the display.
