Description

Известны широкополосные частотные дискриминаторы. Основной недостаток их состоит в смещении нул  дискриминаторной характеристики дискриминатора при изменении входното напр жени  из-за нзменени  условий ;работы магнетрона, клистрона или кристаллического смесител , а также крутизны лампы дискриминатора.Wideband frequency discriminators are known. Their main drawback is the displacement of the discriminator's discriminator characteristic zero when the input voltage changes due to changing conditions, the operation of the magnetron, klystron or crystal mixer, as well as the steepness of the discriminator lamp.

В описываемом дискриминаторе указанный, недостаток устранен путем включени  в анодную цепь усилительной лампы двух режекторных контуров, настроенных на вторую гармонику центральной частоты дискриминатора.In the indicated discriminator, the deficiency is eliminated by inserting into the anode circuit of the amplifying lamp two notch circuits tuned to the second harmonic of the discriminator's central frequency.

На чертеже изображена принципиальна  схема предлагаемого широкополосного дискриминатора.The drawing shows a schematic diagram of the proposed broadband discriminator.

Усилительный каскад дискриминатора содержит лампу 1, в анодную цепь которой включены последовательно два расстроенных контура 2 и 5. Выдел емые контурами напр жени  детектируютс  лампами 4 и 5 и суммируютс  на сопротивлени х 6 и 7. Подавление напр жени  второй гармоники переходной частоты осуществл етс  режекторными контурами 8 и 9, включенными в анодную цепь лампы /. Включение режекторных контуров, настроенных на вторую гармонику переходной частоты, делает нуль дискриминаторной характеристики независимым от изменений входного напр жени .The discriminator amplifier cascade contains a lamp 1, in the anode circuit of which two distorted circuits 2 and 5 are connected in series. The voltages allocated by the circuits are detected by lamps 4 and 5 and summed up to the resistances 6 and 7. The voltage suppression of the second harmonic of the transient frequency is performed by notch circuits 8 and 9, included in the anode circuit of the lamp. The inclusion of notch circuits tuned to the second harmonic of the transition frequency makes the discriminator characteristic zero independent of changes in the input voltage.

Предмет изобретени Subject invention

Широкополосный дискриминатор сдвулЕ  расстроенными контурами, включенными последовательно в анодную цепь усилительной лампы, отличающийс  тем, что, с целью уменьшени  смещени  нул  дискриминаторной характеристики при изменении входного напр жени  и крутизны лампы, в анодную цепь лампы включены два режекторных контура, настроенные на вторую гармонику центральной частоты дискриминатора.The wideband discriminator is biased by detuned circuits connected in series to the anode circuit of an amplifying lamp, characterized in that, in order to reduce the bias of the discriminator characteristic when the input voltage and the lamp slope change, two notch circuits tuned to the second harmonic of the central frequency are changed discriminator.
