Description
(54) УСТРОЙСТВО СИНХРОНИЗАЦИИ(54) SYNCHRONIZATION DEVICE
1one
Изобретение относитс к радиотехнике и может использоватьс в системах передачи дискретной информации с временнйм уплотнением.The invention relates to radio engineering and can be used in systems for transmitting discrete information with a time seal.
Известно устройство синхронизации, содержащее п каналов, каждый из которых состоит из последовательно соединенных входного ключа, первого делител частоты, фазового дискриминатора и усилител , а также управл ющий элемент, объединенный по входу с входным ключом, при этом выходы управл ющего элемента подключены к другим входам входного ключа и первого делител частоты, причем выходы всех каналов подключены к входам сумматора , выход которого через последовательно соединенные фильтр нижних частот, управл емый генератор и второй делитель частоты подключен к другим входам фазовых дискриминаторов и управл ющих элементов всех каналов ij .A synchronization device is known that contains n channels, each of which consists of a serially connected input key, a first frequency divider, a phase discriminator and an amplifier, as well as a control element integrated in the input with the input key, while the outputs of the control element are connected to other inputs the input key and the first frequency divider, the outputs of all channels are connected to the inputs of the adder, the output of which is through a series-connected low-pass filter, a controlled oscillator and a second one frequency fir connected to the other input of the phase discriminator and the actuating elements of all channels ij.
Однако известное устройство обладает низкой надежностью работы в услови х измен ющейс (нестабильности) частоты поступающего синхросигнала и низкой точностью синхронизации.However, the known device has low reliability in the conditions of varying (instability) frequency of the incoming clock signal and low synchronization accuracy.
Цель изобретени - повышение точности синхронизации.The purpose of the invention is to improve the synchronization accuracy.
