Description
задержки соответственно подключен к второму и первому входам смесител 3 и блока 8 измерени , а на приемной стороне - блок 10 дл передачи синхросигнала, причем выход блока 7 подключен к входу блока 10, выход которого через дополнительный канал 11 св зи подключен к еуорому входу блока 8 измерени .delays are respectively connected to the second and first inputs of the mixer 3 and the measuring unit 8, and on the receiving side - the unit 10 for transmitting the clock signal, and the output of the unit 7 is connected to the input of the unit 10, the output of which is connected via an additional channel 11 to the unit 8 measurements.
Система работает следующим образом.The system works as follows.
Групповой сигнал, состо щий из информационного и синхросигнала и формируемый смесителем 3, поступает через блок 4 в капал св зи 5, а затем на объединенные входы блока 6 декодировани информационного сигнала и блока 7 выделени синхросигнала, где производитс обработка этих сигналов. Выделенный в блоке 7 синхросигнал через блок 10 и дополнительный канал 11 св зи поступает на второй вход блока 8 измерени , на первый вход которого поступает сигнал с выхода управл емого элемента 9 задержки. С выхода блока 8 измерени па вход управл емого элемента 9 задержки поступает управл ющий сигнал, который измен ет величину задержки таким образом, что измер ема величина рассогласовани стремитс к нулю. Тем самым в поступающем на смеситель 3 синхросигнале учтена величина задержки сигнала при распространении от передающей до приемной стороны, в результате чего повыщаетс достоверность передачи информации.A group signal consisting of information and a sync signal generated by mixer 3 flows through block 4 into a drop of link 5, and then to the combined inputs of decoding block 6 of the information signal and block 7 of the sync signal where these signals are processed. The sync signal allocated in block 7 through block 10 and the additional communication channel 11 is fed to the second input of measuring unit 8, to the first input of which a signal is output from the controllable delay element 9. From the output of the measuring unit 8, the PA input of the controllable delay element 9, a control signal is received, which changes the delay value so that the measured error value tends to zero. Thereby, the signal delay during propagation from the transmitting side to the receiving side is taken into account in the synchronizing signal arriving at the mixer 3, as a result of which the reliability of information transmission increases.
