摘要
介绍了直接数字频率合成器(Direct Digital frequency Synthesizer,DDS)的基本结构和工作原理,并在此基础上着重论述了利用Matlab软件建立DDS的理想和杂散仿真模型的方法。通过建立仿真模型,可以更方便有效地对DDS杂散分布特点进行分析。
This paper first introduces the structure and fundamental principles of an ideal direct digital frequency synthesizer. Then a method of simulating ideal and spur model of DDS using Matlab is discussed. Using these simulation models, the effect of the spurs on DDS system can be analyzed more effectively.
