DEVICE FOR AUTOMATIC MAINTAINING THE LEVEL OF THE OUTPUT CAPACITY OF A TRANSMITTER,

Abstract

In the applied automatic level control of the output power of the transmitter during telephone work on a single side band with incompleteness of suppressed carrier, the level of high-frequency signal does not remain constant and changes in proportion to the level of the modulating frequency. In the proposed device a memory circuit was applied for memorization of the level of the carrier frequency in the moment of absence of modulation to the moment of appearance of the following pause in modulation. Adjustment of the amplitude of excitation on the intermediate frequency diodes was applied, by connecting the device in series into the divisor circuit, joined to the input of the modulator.
