    • The invention provides signal synchronization systems. The signal synchronization system comprises a plurality of synchronization units and a control unit. The synchronization units each correspond to one transmitting device for accurately transmitting the transmitted data from the transmitting devices to the control unit. The control unit generates a system clock and a data selection signal according to the amount of the transmitting devices. The system clock has to be fast enough to be capable of receiving data from all transmitting devices. The transmitted data is transmitted to the control unit according to the order shown in the data selection signal. The control unit integrates the received data in a single signal named system data signal and further generates a data selection signal to designate a plurality of receiving devices to receive the data in the system data signal. The transmitted data can be accurately transmitted from the transmitting devices to the receiving devices by the signal synchronization system of the invention.
    • 本发明提供信号同步系统。 信号同步系统包括多个同步单元和控制单元。 同步单元各自对应于用于将发送的数据从发送设备精确地发送到控制单元的一个发送设备。 控制单元根据发送装置的数量生成系统时钟和数据选择信号。 系统时钟必须足够快以能够从所有发送设备接收数据。 发送的数据根据​​数据选择信号所示的顺序发送到控制单元。 控制单元将接收到的数据集成在一个名为系统数据信号的单个信号中,并进一步产生数据选择信号以指定多个接收装置以接收系统数据信号中的数据。 可以通过本发明的信号同步系统将发送的数据从发送装置精确地发送到接收装置。
