说明：  介绍了一种基于DDS/ SOPC技术的谐波信号发生器的设计方案, 详细论述了DDS的 工作原理及SOPC的设计过程。在设计中将DDS模块和MCU模块集成到一个单片FPGA上, 使设计出的系统具有集成度高、灵活性好等优点。
(This paper presents a design of harmonic signal generator based on DDS/SOPC technology, particularly discussed the principle of DDS and the design course of SOPC. This design integrated DDS module and the MCU module on a single FPGA chip .So the performance such as integration, expansibility improved much.)
