Description
(54) УСТРОЙСТВО ДЛЯ ФОРМИРОВАНИЯ ИМПУЛЬСОВ СИНХРОНИЗАЦИИ ПРИ ВОСПРОИЗВЕДЕНИИ С НОСИТЕЛЯ (54) DEVICE FOR THE FORMATION OF SYNCHRONIZATION PULS DURING PLAYBACK FROM MEDIA
II
Изобретение относитс к магнитной записи, а именно к устройствам дп фор мировани импульсов синхронизации при воспроизведении с носител магнитной записи.The invention relates to magnetic recording, in particular, to devices for forming synchronization pulses during playback from a magnetic recording medium.
Известно устройство дп формировани импульсов синхронизашш при воспроизведении с носител магнитной записи, содержащее входную шину воспроизведенного сигнала, соединенную через формирователь , синхросигнала с выходной шиной импульсов синхронизации Г1 .A device dp of forming synchronous pulses during playback from a magnetic recording medium is known, which comprises an input bus of a reproduced signal connected via a driver to a synchronization signal with an output bus of synchronization pulses G1.
Данное устройство имеет относительно простую конструкцию, однако не позвол ет обеспечить формирование импульсов сиюфонизашш при воспроизведении сигнала , записанного на носителе магнитной записи с достаточно вьгоокой плотностью.This device has a relatively simple design, however, it does not allow for the formation of pulses from a reproduction signal recorded on a magnetic recording medium with a sufficiently high density.
Известно также устройство дл формировани импульсов синхронизации при воспроизведении с носител магнитной записи, содержащее входную шину воспроизведенного сигнала, подключенную ко входу демодул торй , генератор импульсов, выМАГНИТНОЙ ЗАПИСИIt is also known a device for generating synchronization pulses during reproduction from a magnetic recording medium, comprising an input bus of a reproduced signal connected to the input of a demodulator, a pulse generator, and a MAGNETIC RECORDING
ход которого подключен к первому входу блока формировани сигнала рассогласовани и ко входу управл емого счетчика, подсоединенного выходом к выходной шине импульсов синхронизапии, триггер, блок задержки, аналоговый инвертор, элемент ИЛИ к элемент И. Это устройство позвол ет обеспечить формирование импульсов синзфонизашш при воспроизведении сигнала, записанного на носителе магнитной записи с достаточно высокой плот ностью С 2.the stroke of which is connected to the first input of the error signal shaping unit and to the input of the controlled counter connected to the output bus of the synchronization pulses, a trigger, a delay unit, an analog inverter, an OR element to the element I. This device allows the formation of synchro-pulse during playback of the signal recorded on a magnetic recording medium with a sufficiently high density of C 2.
Недостаток данного устройства состоит в значительной погрешности формврованн импульсов синхронизации при воспроизве15 дении с ноо1теп : магнитной записи.The disadvantage of this device consists in a significant error in the formation of synchronization pulses during reproduction with noto: magnetic recording.
Цель изобретени - уменьшение погрешности формировани импульсов синхронизации при востфоизведении с носител магнитной записи.The purpose of the invention is to reduce the error in the formation of synchronization pulses when extracting from magnetic recording media.
