Изобретение относитс к технике электросв зи и может использоватьс в многоканальных системах передачи, предназначенных дл передачи сигналов изображени .The invention relates to telecommunications engineering and can be used in multichannel transmission systems for transmitting image signals.
Известно устройство дл синхрони зации генераторов псевдослучайной последовательности канала св зи, содержащее на передаче первый дешифратор , входы которого соединены с выходами соответствующих разр дов регистра сдвига первого генератора псевдослучайной последовательности, задающий генератор и формирователь импульсов запуска, вход которого вл етс входом сигнала пуска, а выход соединен с установочным входом регистра сдвига первого генератора псевдослучайной последовательности, а на npMieме - последовательно соединенные второй дешифратор, входы которого соединены с выходами соответствующих Vразр дов регистра сдвига второго ге нератора псевдослучайной последовательности , и ключ и последовательно соединенные сумматор по модулю два и делитель частоты, выход которого и первый и второй входы сумматора по модулю соединены соответственно с первым и вторым входами ключа вто-. рого генератора псевдослучайной последовательности и с выходом канала св зи lj.A device is known for synchronizing pseudo-random communication channel sequence generators, which contains a first decoder in the transmission, the inputs of which are connected to the outputs of the corresponding bits of the shift register of the first pseudo-random sequence generator, the master oscillator and the trigger driver, whose input is the start signal input, connected to the setup input of the shift register of the first pseudo-random sequence generator, and on the npMieme - serially connected seconds oh decoder, the inputs of which are connected to the outputs of the corresponding V bits of the shift register of the second pseudo-random sequence generator, and the key and the modulo two and a frequency divider serially connected, whose output and the first and second inputs of the modulo adder are connected respectively to the first and second keys inputs vto- pseudorandom sequence generator and with the output of the communication channel lj.
Однако известное устройство имеет длительное врем синхронизации.However, the known device has a long synchronization time.
Цель изобретени - сокращение времени синхронизации.The purpose of the invention is to reduce the synchronization time.
