  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To decrease the distortion greatly by inserting the load variable resistance element between the grounded emitter transistor's collector to amplify the input signal and the power voltage supply point and then controlling the resistance of the resistance element in accordance with the output voltage of the transistor.
