  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To avoid the oscillation as well to increase the variable range of the gain for the gain control amplifier containing 4 units of transistors Tr, by connecting the emitters between the first and fourth Tr's and then earthing them via the diode or the resistance.
