摘　　要：数字复接技术是现代数字通信中常用的技术。本文给出了一种采用时分复用技术,基于FPGA对语音、同步数据、异步数据等多路不同等级数字信号进行复分接设计与实现的方法,对设计与实现过程关键技术进行了详细的论述,同时对设计中需要注意的问题做了必要的说明。The digital multiple connection technology is commonly used in the modem digital communication. Using the time- sharing multiplying technology, based on FPGA, this article gave one kind of duplicate design and the realization method for the pronunciation, the synchro data, the asynchronous data and so on the multi-channel different rank digital signal. Key to designed has carried on the detailed elaboration with the realization process key technologies, simultaneously to designed the question which needed to pay attention to give the essential explanation.
