Description
(54) УСТРОЙСТВО СИНХРОНИЗАЦИИ ПО ПОСЫЛКАМ(54) DEVELOPMENT SYNCHRONIZATION ON THE POSITIONS
Изобретение относитс к технике |синхронной св зи .и может быть использовано в приемных устройствах дл синхронизации по посылкам.The invention relates to a synchronous communication technique. And it can be used in receiving devices for sending synchronization.
Известно устройство синхрониза-. ции по посылкам, содержащее объединенные -по первому входу два перемножител , к вторым входам которых подключены выходы генератора опорных сигналов, а также два реверсивных счетчика, пр мые и обратные выходы которых объединены и подключены к входам блока сравнени , выход которого подключен ко входу генератора опорных сигналов, при этом дополнительные выходь реверсивных счетчиков подключены к входам дешифраторов , выходы которых подключены к управл ющим входам реверсивных счетчиков fl.Known device sync. by the first input, two multipliers, to the second inputs of which are connected the outputs of the reference signal generator, as well as two reversible counters, the forward and reverse outputs of which are combined and connected to the inputs of the comparison unit, the output of which is connected to the input of the reference generator signals, while the additional outputs of the reversible counters are connected to the inputs of the decoders, the outputs of which are connected to the control inputs of the reversible counters fl.
Недостатком известного устройства. &1 етс наличие ложных сдвигов ( в направлени х от синфазного состо ни ) при работе по посылкам произвольной кодовой комбинации, что приводит к снижению точности синхронизации и уменьшению времени вхождени в синхронизм.The disadvantage of the known device. & 1 the presence of spurious shifts (in the directions from the common-mode state) when working on the premises of an arbitrary code combination, which leads to a decrease in the synchronization accuracy and a decrease in the time to synchronization.
Цель изобретени - повышение точности синхронизации и уменьшение времени вхождени в синхронизм.The purpose of the invention is to improve the synchronization accuracy and reduce the time of entry into synchronism.
