Description
(54) УСТРОЙСТВО ФОРМИРОВАНИЯ БЛАНКИРУЮи|ЕГО ИМПУЛЬСА(54) DEVICE FORMATION OF BLANKING AND ITS PULSE
1one
Изобретение относитс к технике св зи и может использоватьс .в аппаратуре автоматического регулировани , в аппаратуре , котора работает в услови х действи импульсных помех.The invention relates to communication technology and can be used in automatic control equipment, in equipment that operates under the conditions of impulse noise.
Известен помехоподавл юший фильтр дл приемника частотномодулированныт; сигналов, в котором к выходу ЧМ- адскриминатора подключен резонансный контур дл отделени компоненты помех, импульс- д кого вида, спектр которых лежит выше полосы тональных сигнале. К резонансHOKiy контуру подключен дифференютальный усилитель с фильтром верхних частчэт и элемент ИЛИ дл передачи выходного js сигнала с требуемым знаком дифференциального усилител с фильтром высоких частот на электронный ключ tl .Known interference suppression filter for receiver frequency modulated; signals, in which a resonant circuit is connected to the output of the FM ad- criminator to separate the interference components of a pulse type whose spectrum lies above the tonal signal band. A differential amplifier with a high-pass filter and an OR element is connected to the resonance of the TOKiy circuit for transmitting the output js signal with the required sign of the differential amplifier with a high-pass filter to the electronic switch tl.
Недостатком данного устройства вл етс то, что оно примен етс , когда по- 20 меха либо с известными или квазидетерминированными параметрами, так как при неизвестных, случайных параметрах это устройство применить дл выделени импульсной помехи из смеси ее с сигналом не представл етс возможным.The disadvantage of this device is that it is used when there are furs with either known or quasi-deterministic parameters, since with unknown, random parameters this device cannot be used to extract impulse noise from the mixture with the signal.
Известно устройство формировани бланкирующего импульса дл радиоприемника , содержащее первое устройство дифференшфовани сигнала, усилитель, выпр мнтелЬ{ второе устройство дифференцировани и ключ с накопителем 2 ,A device for forming a blanking pulse for a radio receiver is known, comprising a first signal differentiating device, an amplifier, a rectifier {second differentiation device and a key with drive 2,
Недостатком ,данного устройства вл етс невозможность выделени помехи при неизвестных, случайных, параметрах импульсной помехи.The disadvantage of this device is the impossibility of interfering with unknown, random, impulse noise parameters.
Цель изобретени - повьпиение достоверности выделени импульсных помех з их смеси с сигналом при неизвестных случайных параметрах помехи.The purpose of the invention is to increase the reliability of the emission of impulse noise from their mixture with a signal with unknown random parameters of interference.
