Сигналрграмма состоит из радиоимпульсов 12 и шумов 13 паузы. Выделенные вырезки из продетектированных шумов 13 и радиоимпульсов наход тс в зонах, имеющих границы 14 и 15. .Выделений происходит после олйнчани переходных процессов, вызванных прохо ждением радиоимпульсов через каналThe signalgram consists of radio pulses 12 and noise 13 pauses. The selected clippings from the detected noise 13 and radio pulses are located in the zones having boundaries 14 and 15. The precipitates occur after the transients are caused by the passage of radio pulses through the channel

And. detectors 5. Circuits b, also controlled by block 7, are cut from sequentially detected pause noises and detected radio pulses, which are then integrated. It is necessary to take into account that PS is the time of the discharge of integrators with closed circuits, much more than ampoules than with open ones. Therefore, gfbintegrirovannye cuts, which characterize the magnitude of the loop and pause, through the bumper, ymey) 1Without the input resistance, are fed to different inputs of the unit 10 tolerance control. The output indicator generates information like YES, or
НЕТ, чть означает пригодность или непригодность контролируемого объекта.NO, Pt means the suitability or unsuitability of the controlled object.
Реализаци способа позвол ет использовать на лини х контрол опера5 тора низкой квалификации, повысить качество контролируемых магнитофонов и увеличить скорость контрол .The implementation of the method makes it possible to use an unqualified operator on the control lines, to improve the quality of controlled tape recorders and to increase the speed of control.
