Description
Известные схемы телевизионных синхрогенераторов с синхронизацией частоты полей частотой питающей сети не обеспечивают высокую устойчивость работы.The known schemes of television synchro-generators with synchronization of the frequency of the fields with the frequency of the supply network do not provide high stability of operation.
В предлагаемом способе указанный недостаток устран етс путем применени делител частоты с регулируемым коэффициентом делени . Задающий генератор (генератор двойной строчной частоты) работает на фиксированной частоте. В качестве делител частоты задающего генератора примен етс последовательное соединение триггерных двоичных чеек. Частота импульсов полей с выхода делител сравниваетс с частотой питаюплей сети в фазовом дискриминаторе.In the proposed method, this disadvantage is eliminated by using a frequency divider with an adjustable division factor. The master oscillator (double line frequency generator) operates at a fixed frequency. A serial connection of trigger binary cells is used as the frequency divider of the master oscillator. The frequency of the field pulses from the output of the divider is compared with the frequency of the supply network in the phase discriminator.
Ждущий мультивибратор запускаетс импульсами полей и управл етс фазовым дискриминатором так, что длительность импульсов мультивибратора пропорциональна выходному напр жению дискриминатора. Эти импульсы подаютс на один из триггеров делител , перевод его в режим усилени запускающих импульсов, и тем самым, уменьшают коэффициент делени делител , пока частота полей не сравн етс с частотой сети.The waiting multivibrator is triggered by field pulses and controlled by the phase discriminator so that the pulse duration of the multivibrator is proportional to the output voltage of the discriminator. These pulses are applied to one of the splitter triggers, switching it to the trigger pulse amplification mode, and thereby reducing the divider division ratio until the field frequency equals the network frequency.
Синхронизатор может работать как в ведомом, так в автономном режимах .The synchronizer can operate in both slave and offline modes.
