Description

Translated fromRussian

вать форму АЧХ приемника путем вы влени  закона изменепи  огибающей напр жени  в цепи автокомпенсатора 10 в функции от частоты входного сигнала.Form the receiver's frequency response by detecting the law of variation of the voltage envelope in the autocompensator circuit 10 as a function of the frequency of the input signal.

Сигнал с выхода детекторной головки 9, пропорциональный интенсивности только измерительного ЧМ сигнала на выходе приемника , ноступает па один из входов датчика п. На второй вход датчика отношени  подаетс  сигнал с выхода амплитудного детектора , обусловленный только шумами приемника . На выходе датчика 11 образуетс  напр жение , пропорциональное отношепию сигнал/шум на выходе приемного тракта, периодически измен ющеес  по амплитуде по мере сканировани  измерительного ЧМ сигнала по полосе пропускани  приемника.A signal from the output of the detector head 9, proportional to the intensity of only the measuring FM signal at the receiver output, is not received at one of the sensor inputs of the sensor. To the second input of the ratio sensor, a signal is output from the amplitude detector, due only to the noise of the receiver. The output of sensor 11 produces a voltage proportional to the signal-to-noise ratio at the output of the receiving path, periodically varying in amplitude as the measuring FM signal is scanned over the receiver bandwidth.

Истинна  чувствительность приемника определ етс  максимальным значением напр жени  на выходе датчика //. Подача на регистрирующее устройство 13 этого экстремальиого напр жени  обеспечиваетс  работой ключевого элемента 12, наход щегос  в нормально закрытом состо нии.The true receiver sensitivity is determined by the maximum voltage value at the output of the sensor, //. The supply to the recording device 13 of this extreme voltage is ensured by the operation of the key element 12, which is in the normally closed state.

Формирователь импульса строба 14 вырабатывает импульс лишь в момент равенства частоты сканируемого измерительного напр жени  собственной частоте приемника, что достигаетс  внешней синхронизацией. Именно в эти моменты импульсы строба отпирают ключевой элемент 12 и напр жение с датчика //The pulse shaper 14 produces a pulse only when the frequency of the scanned measuring voltage is equal to the natural frequency of the receiver, which is achieved by external synchronization. It is at these moments that the strobe pulses unlock the key element 12 and the voltage from the sensor //

отношени  поступает на вход регистрирующего устройства 13.The ratio is fed to the input of the recording device 13.
