摘要
首先介绍了直接数字合成(DDS)技术的基本原理,并分析了工程实际中DDS的误差信号来源。在此基础上着重论述了利用软件建立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。
The basic principle of the direct digital synthesis （ DDS） is introduced firstly in this paper. The error signal in engineering is analyzed. On this basis,a method which uses software to establish the DDS ideal and stray simulation model is discoursed. Through the establishment of the simulation model,DDS stray distribution characteristics can be more easily and effectively analyzed.
