摘要
为提高数字通信系统的信道利用率及准确率,文中提出了一种8路数字信号的复接分接系统设计方案。方案主要采用乒乓操作解决低速数据采集高速输出的数据丢失问题。并且基于Quartus II 11.0软件完成了方案的复接分接系统设计与仿真,通过在Altera的EPM570T100C5N芯片上进行测试。实验结果表明,设计正确且稳定,可应用于多路数字信号通信的实验教学。
Digital multiplex and de -multiplexing is an important technique in digital communication. In order to improve channel utilization and accuracy of the digital communication system. This paper introduces the 8 road dig- ital multiplexer and de - multiplexer system design scheme. It mainly uses the ping - pang operation solve the prob- lem of low speed data acquisition high speed output data loss. And based on software QuartusII 11.0 completed the multiplexer and de -multiplexer system design and simulation,and finally in Ahera EPM570T100C5N chip was test- ed. The design is stable and flexible. The experimental results show that the design can be applied to multi - channel digital signal communication in communication experiment teaching.
