Description

Предлагаетс  устройство дл  получени  импульсных электрических колебаний , модулированных по продолжительности при помощи электронного коммутатора с контактной ламелью или ламел дш. Согласно изобретению с целью осуществлени  модул ции за счет изменени  скорости движени  электронного луча по ламели в качестве указанного коммутатора прил1енена электронно-лучева  трубка с одной парой отклон ющих пластин, на которые поданы одновременно напр жени  модулируемых и модулирующих колебаний и которые осуществл ют колебание луча в одной плоскости. Устройство можэт быть использовано в качестве преобразовател  частоты , дл  чего в цепь контактной ламели включают нагрузку, настроенную на разностную частоту колебаний гетеродина и сигнала, суммарное напр жение которых подано на отклон ющие пластины трубки. Кроме того, устройство может быть использовано в качестве электронного усилител , дл  чего в цепь конt/ ,2 t/.(l + тактной ламели включают нагрузку, настроенную на частоту усиливаемых колебаний, напр жение которых подано одновременно с напр жением гетеродина на отклон ющие пластины трубки. На чертеже представлена электрическа  блок-схема предлагаемого устройства. Способ по.пучени  колебаний, модулированных по продолжительности, основан на применении в качестве модул тора безинерционной системы, в которой продолжительность импульсов определ етс  амплитудой моду-,, лирующего напр жени , а частота- частотой модулируемого напр жени . В качестве такого безинерционного модул тора по продолжительности используют электронный коммутатор, на отклон ющие пластины 7 и 2 которого подвод т модулируемое и модулирующее колебани  либо в виде колебани , модулированного по амплитуде , либо раздельно. В обоих случа х результирующее колебание, отклон ющее электронный луч, можно представить как: sin Dl cos ((of - 9).A device is proposed for producing pulsed electrical oscillations modulated in duration using an electronic switch with a contact lamella or lamellae. According to the invention, in order to effect modulation by varying the speed of the electron beam, a cathode ray tube with a single pair of deflecting plates, simultaneously applied to the voltage of the modulated and modulating oscillations and which oscillate the beam in one plane. The device can be used as a frequency converter, for which the load on the contact lamella circuit is tuned to the differential frequency of oscillation of the local oscillator and signal, the total voltage of which is applied to the deflection plates of the tube. In addition, the device can be used as an electronic amplifier, for which the circuit 2t /. (L + time lamella includes a load tuned to the frequency of amplified oscillations, the voltage of which is applied simultaneously with the voltage of the local oscillator The drawing shows an electrical block diagram of the device proposed. The method for extracting oscillations modulated in duration is based on using a zero-inertia system as a modulator, in which the duration of the pulses is is limited by the amplitude of the modulating voltage, and by the frequency by the frequency of the modulated voltage. As such an inertia-free modulator, an electronic switch is used for the duration, on the deflecting plates 7 and 2 of which a modulated and modulating oscillation is applied, either in the form of an oscillation modulated in amplitude or separately. In both cases, the resulting oscillation deflecting the electron beam can be represented as: sin Dl cos ((of - 9).
