Abstract

PURPOSE:To secure a free variation for the level of the output voltage, by dividing the area between the input and output terminals of the gain control circuit with two units of the resistance, connecting the input electrode of the transistor to the division point, connecting the output electrode of the transistor to the output terminal, and changing the division ratio for the division point.
