摘要

in multiple separate devices , detect a phase difference from the reference frequency and the reference frequency of the input and output of each system of multiple signals on the basis of the phase difference detected by the phase difference detection , a phase difference detection section that , with respect to transmitting and receiving digital signals from each of the input and output system , a time corresponding to the phase difference between the shifted each input and output system interpolates the signal , and by the reference frequency of the multiplexed signal and the interpolation unit for acquiring transmission digital signal for each output sampling getong , the transmitting and receiving digital signals for each input and output system using the reference frequency of the multiplexed signal established a signal multiplexing or demultiplexing to separate .
