Известны способы регистрации характеристических .моментов восстановлени телеграфных сигналов на экране электронно-лучевой трубки измерительного прибора с линейной разверткой. Маркировку характеристических моментов в подобных способах осуществл ют всплесками луча, отличающимис по форме. Визуальный отсчет на экранах трубок при этом затруднителен. Кроме того, в известных способах не предусмотрена возможность измерени дроблений телеграфных посылок.Methods are known for recording the characteristic moments of reconstructing telegraphic signals on the screen of a cathode ray tube of a measuring instrument with a linear scan. The marking of the characteristic moments in such methods is carried out by bursts of the beam that differ in shape. The visual counting on the screens of the tubes is difficult. In addition, in the known methods, it is not possible to measure the crushing of telegraph parcels.
В описываемом способе указанные недостатки устранены путем маркировки характеристических моментов всплесками луча вверх или вниз и отсчета продолжительности дроблений по импульсам меток, значительно превышающих скорость телеграфировани .In the described method, these drawbacks are eliminated by marking the characteristic moments with bursts of the beam up or down and counting the duration of the splittings by tag pulses, which are much higher than the speed of wiring.
Использована также линейна временна развертка принимаемых сигналов напр жением треугольной формы. В течение каждого элементарного импульса луч пробегает от центра экрана до правого его кра , затем от правого кра до левого, после чего возвращаетс к центру экрана в исходное положение. Регистраци характеристических моментов восстановлени осуществл етс кратковременным всплеском луча. При этом в первой и четвертой четверти развертываемого элементарного импульса всплеск луча нанравлен вверх, а во второй и третьей четверти - вниз.A linear time sweep of received signals by a triangular voltage was also used. During each elementary pulse, the beam runs from the center of the screen to its right edge, then from the right edge to the left, and then returns to the center of the screen to its original position. The recording of the characteristic recovery moments is carried out by a short burst of the beam. At the same time, in the first and fourth quarters of the developable elementary impulse the surge of the beam is directed upwards, and in the second and third quarters - downwards.
Регистраци дроблений типа отсутстви тока сигнала «а входе измерительного прибора происходит за счет вспомогательных импульсов (меток). Эти метки подают на электроды электронно-лучевой трубки. Частота меток значительно превыщает скорость телеграфировани измер емой последовательности 1 мпульсов.The recording of splittings of the type of absence of a current signal “at the input of the measuring device occurs at the expense of auxiliary pulses (marks). These tags are fed to the electrodes of the cathode ray tube. The frequency of the tags greatly exceeds the wiring speed of the measured sequence of 1 mp.
По количеству импульсов (меток) суд т о продолжительности дроблени .By the number of pulses (marks), the duration of the crushing is judged.
№ 13.428, 2 Предмет изобретени No. 13.428, 2 The subject invention
Сггособ регистрации характеристических моментов восстановдени телеграфных сигналов на экране электронно-лучевой трубки измерительного прибора с линейной временной разверткой сигналов напр жением треугольной- формы, отличающийс тем, что, с целью улучшени визуального отсчета искажений и продолжитель юсти дроблений, характеристические моменты восстановлени в периоды пр мого хода луча развертки маркируют всплеском луча вверх, а в. периоды обратного хода - всплеском луча вниз, в периоды отсутстви тока сигнала на электроды электронно-лучевой трубки подают импульсы меток, по частоте следовани значительно превышающие скорость телеграфировани .The method of recording the characteristic moments of the recovery of telegraphic signals on the screen of the cathode ray tube of a measuring instrument with a linear time signal sweep of signals with a triangular-shaped voltage, characterized in that, in order to improve the visual counting of distortions and the continuity of crushing, the characteristic moments of recovery in forward periods scan beam mark a burst of the beam up, and in. periods of reverse - a burst of the beam down, during periods of no current signal to the electrodes of the cathode-ray tube, pulses of marks are supplied, which in terms of the frequency of the signal are much higher than the speed of wiring.
