Abstract

PURPOSE: To obtain a carrier-zero level and an AGC reference voltage by providing a resistance to the emitter of a transistor applied at its base with the divided voltage of a power voltage.
CONSTITUTION: Series resistances R3 and R4 constitute the power-voltage divider and from the emitter of transistor TrQ1 applied with this divided voltage at its base, a carrier-zero level is developed. To the emitter of TrO1, resistance R1 is provided and its other terminal is connected to the collector of constant-current TrQ2. To the base of TrQ2, a divided voltage by resistances R5 and R6 is applied and resistance R2 is provided to emitter so as to obtain a constant current. The collector voltage of this TrQ2 is used as an AGC reference potential.
