Description

При прохождении мимо головки заднего фронта намагниченного участка магнитной ленты на ее выходе вырабатываетс  отрицательный импульс, возвращающий триггер в исходное состо ние. Если до этого момента на интеграторе напр жение плавно нарастало , то после ноступлени  отрицательного имнульса па выходе интегратора напр жение прекращает нарастать и остаетс  некоторое врем  посто нным. Однако теперь по вл етс5 импульс иа выходе схемы совнадени , который запускает релаксатор 11, перевод щий своим сигналом ключ 5 в состо ние нроводимости . Далее в заданный промежуток времени сигнал с выхода интегратора поступает на вход заноминающего блока 6 и с него на выходные зажимы. По истечении этого промежутка времени ключ 5 возвращаетс  в исходное разомкнутое состо ние, а выходное напр жение запоминаетс  до следующего интервала замыкани  ключа.When passing past the head of the rear edge of the magnetized section of the magnetic tape, a negative impulse is generated at its output, which returns the trigger to its initial state. If up to this point on the integrator, the voltage gradually increased, then after the negative impulse was received on the integrator output, the voltage stopped increasing and remained for some time constant. However, now there is a 5-pulse of the output of the scheme of the community, which triggers the relaxer 11, which translates the key 5 into the state of conduction with its signal. Next, at a predetermined period of time, the signal from the integrator output is fed to the input of the memory block 6 and from it to the output terminals. After this time period expires, key 5 returns to its original open state, and the output voltage is stored until the next key closure interval.
