Abstract

PURPOSE: To obtain a circuit superior in operational efficiency which can be preset and has an up/down capability of tuning operations, by utilizing the long-time memory of an analogue voltage in the auto-search tuning using an electronic tuner.
CONSTITUTION: When signal strength signal SA and frequency discrimination signal SF are inputted from a receiver to signal detection part 3 and a certain condition is satisfied, the output is issued to stop pulse generator 5, and analogue memory 1 holds the voltage for a long time, thereby performing a stable receiving. In this operation, pulses of pulse generation part 5 are counted by counting part 7, and the counted value is stored in storage part 8. As a result, the stored channel is called and preset.
