Description
Изобретение касаетс схемы, позвол ющей получить бесшумную и задержанную автоматическую регулировку СИЛЫ (А.Р.С.) в приемниках с диодным демодул тором, собранным ло схеме удвоени напр жени .The invention relates to a circuit that allows obtaining a silent and delayed automatic adjustment of the POWER (ARS) in receivers with a diode demodulator assembled in a voltage doubling circuit.
Схема предлагаемого устройства показана на чертеже.The scheme of the proposed device is shown in the drawing.
Напр жение сигнала высокой частоты с контура К подано на два диода одновременно. При этом анод одного диода н катод другого соединены вместе и присоединены к одному из концов контура. .The high-frequency voltage from circuit K is supplied to two diodes simultaneously. In this case, the anode of one diode and the cathode of the other are connected together and connected to one of the ends of the circuit. .
На сопротивлени х RI и обоих диодов напр жени низкой частоты сложатс и мы будем иметь удвоение напр жени .On the resistances of the RI and both diodes, the low frequency voltage will fold and we will have a doubling of the voltage.
С целью получени при такой схеме демодул тора бесшумной и задержанной автоматической регулировки силы {А. Р. С.), в цепь левого диода введен источник отрицательного напр жени ; например, в качестве такого источника использовано сопротивление RI, через которое протекает посто нный ток соответствующего направлени .In order to obtain, with such a demodulator circuit, a silent and delayed automatic force control {A. R.S.), a source of negative voltage is introduced into the left diode circuit; For example, the source of resistance is RI, through which the direct current flows in the corresponding direction.
Отрицательное напр жение, введенное в цепь катода левого диода, одновременно с удваивающим диодом, запирает и правый демодулирующий диод, так как за мкнутую цепь выпр мленного тока образуют оба последовательно включенных диода.The negative voltage introduced into the cathode circuit of the left diode simultaneously with the doubling diode also locks the right demodulating diode, since the closed circuit of the rectified current forms both series-connected diodes.
А. Р. С. и демодул ци , при такой схеме включени , будут иметь место ТОЛЬКО ДЛЯ сигналов, амплитуда несущей частоты которых будет превышать задерживающий потенциал.A. P. S. and demodulation, with such a switching scheme, will take place ONLY for signals, the amplitude of the carrier frequency of which will exceed the delay potential.
Порог бесшумности, а значит и порог задержки, могут быть регулируемы изменением величины запирающего потенциала.The silence threshold, and hence the delay threshold, can be controlled by varying the magnitude of the blocking potential.
Предмет изобретени .The subject matter of the invention.
Устройство ДЛЯ получени бесшумной и задержанной автоматической регулировки СИЛЫ (А. Р. С.) в приемниках с диоднУм демодул торомудвоителем напр жени , отличающеес тем, что задерживающее напр жение приложено к цепи катода диода-удвоител напр жени .A device for obtaining a silent and delayed automatic adjustment of the FORCE (A. P. C.) in receivers with a diode demodulator voltage amplifier, characterized in that a delay voltage is applied to the cathode circuit of a voltage doubler diode.
