Description

Изобретение относитс  к дискриминаторам нулевых биений.This invention relates to zero beat discriminators.

Известные схемы дискриминаторов нулевых биений имеют малую полосу захватывани , что ограничивает область их применени .The known schemes of zero beat discriminators have a small capture band, which limits their field of application.

В описываемом изобретении этот недостаток устранен тем, что вместо мультивибратора в дискриминаторе применен ограничитель и парафазньпг усилитель.In the described invention, this disadvantage is eliminated by the fact that instead of a multivibrator, a limiter and a paraphasic amplifier are used in the discriminator.

В описываемом дискриминаторе нулевых биений колебани  разностной частоты со смесителей постунают на вход усплител -ограиичител  обеснечиваюп1его двухстороннее ограничение колебаний при большом усилении.In the zero-beat discriminator described here, the oscillations of the difference frequency from the mixers post-drive to the input of the handler are limited and the reader can reduce the two-sided limitation of the oscillations with a large gain.

С выхода одного усилител -ограничител  напр жение в виде импульсов малой длительности через дифференциальную цепочку поступает на сетку нарафазного усилител . В анодной и катодной цеп х последиего образуютс  напр жени  с амплитудой, равной амплитуде напр жени , поступающего на сетку.From the output of a single amplifier-limiting device, the voltage in the form of short-duration pulses through the differential circuit enters the grid of a single-phase amplifier. In the anodic and cathodic circuits, voltage is then generated with an amplitude equal to the amplitude of the voltage applied to the grid.

Колебани  с нарафазного усилител  поступают на аноды двух диодов , где взаимодействуют с колебани ми , поступающими со второго усилител -ограничител . При этом, вследствие пр люугольной формы этих колебаний, фазова  ошибка в приходе импу.чьсов не сказываетс  на работе диодиого каскада, а с:гедовате.1ьно, и всего дискриминатора .Oscillations from an off-phase amplifier come to the anodes of two diodes, where they interact with the oscillations coming from the second amplifier-limiter. At the same time, due to the rectangular shape of these oscillations, the phase error in the arrival of impulses does not affect the operation of the diode cascade, but from the headspace, and the entire discriminator.
