Description
УСТРОЙСТВО DEVICE
Дл исключени перерывов св зи при подборе телеграфных балансов во врем работы предлагаетс сигнализационное устройство, с помощью которого определ етс разность положительных и отрицате. ьных амплитуд телеграфного тока по их максимальной величине при расстройке балансов.In order to eliminate interruptions in the selection of telegraph balances during operation, a signaling device is proposed by which the difference between positive and negative is determined. the amplitudes of the telegraph current at their maximum value during detuning balances.
Отличительной особенностью предлагаемого устройства вл етс применение коммутатора, работающего синхронно с передатчиком и присоедин ющего плечи дуплексной схемы к амплитудному дискриминатору . Амплитудный дискриминатор состоит из четырех выпр мителей и подключенных к нему двух конденсаторов. Один Конденсатор зар жаетс до амплитудного значени напр жени одного знака, а второй - - до амплитудного значени напр жени другого знака. По прибору, измер ющему разность этих напр жений, можно судить о величине расстройки .A distinctive feature of the proposed device is the use of a switch operating synchronously with a transmitter and connecting the shoulders of a duplex circuit to an amplitude discriminator. The amplitude discriminator consists of four rectifiers and two capacitors connected to it. One capacitor is charged to the amplitude value of a voltage of one character, and the second is charged to the amplitude value of a voltage of another sign. The device measuring the difference of these stresses can be used to judge the magnitude of the mismatch.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Коммутатор /, работающий синхронно с передатчиком, вл етс промежуточным прибором между плечами дуплексной схемы и амплитудным дискриминатором 2. Амплитудный дискриминатор 2 состоит из твердых выпр мителей и копденсаторов Ci и €2. При нажатии ключа / в случае расстройки разность напр жений на конденсаторах С и Cz отмечаетс индикатором 5; конденсаторы разр жаютс на его рабочую обмотку.The switch / operating synchronously with the transmitter is an intermediate device between the shoulders of the duplex circuit and the amplitude discriminator 2. The amplitude discriminator 2 consists of solid rectifiers and capacitors Ci and € 2. When the key is pressed (in the case of detuning), the voltage difference across capacitors C and Cz is indicated by indicator 5; capacitors are discharged to its working winding.
