Abstract
PURPOSE: To make corrections by an AFC voltage, by applying a tuning voltage read out from an analog memory to a turner through a buffer memory.
CONSTITUTION: With preset channel selection switch 14 operated, a turing voltage is read out. A coarse tuning voltage and fine tuning voltage read out from memories 20a and 20b are applied to adder 24, whose output voltage is written in buffer memory 107. Normally, tuning voltages are applied to a tuner after being corrected by an AFC signal from AFC circuit 106. Tuning voltages are being applied to memory capacitor C through the buffer. In accordance with the level of an AFC voltage, charge or discharge of capacitor C is done to hold tuning voltages invariably at the best levels.
