摘　　要：分析了DDS技术的基本原理和基本结构,介绍了一种基于FPGA的DDS信号发生器设计方法。以FPGA芯片EP2C35F672C8为核心器件,辅以必要的模拟电路,在Quartus II9.0平台下实现系统设计的综合与仿真。实验测试表明该信号发生器输出的波形具有平滑、稳定度高和相位连续等优点,具有一定的工程实践意义。The basic principle and the basic structure of DDS technology are analyzed in this paper, which introduces a design method of DDS signal generator based on FPGA. The FPGA chip EP2C35F672C8 is used as the core cell, supplemented by necessary analog circuit. In the Quartus II9.0 platform,synthesis and simulation of the system design is realized. The experiment test shows that the output waveform of the signal generator has the advantages of smooth, high stability and phase continuous, etc. It has a certain engineering practice significance.
