Improvements in Detection, Gain-Control, and Audio-Driver Circuits of Transistorized Broadcast-Band Receivers

This paper describes the use of a new semiconductor device, a diode-triode transistor, to improve detection, automatic gain control, and audio amplification in transistorized broadcastband receivers. The use of this developmental device increases the detector efficiency of battery-operated broadcast-band receivers and permits a minimum number of component parts to be used.
