Abstract

A low frequency detector-amplifier mounting arrangement made with the aid of a unipolar transistor, or field effect transistor, characterized mainly by the fact that the unipolar transistor is excited between the grid and the source by the modulated signal provided by a source of high impedance, the circuit also comprising a resistance and a capacity to detect the modulation, the consumption circuit being charged by a resistance of the terminals from which both the detected and amplified low frequency and the amplified voltage necessary are taken , for the automatic control of the gain of the stages of the amplifier preceding the detection.
