基于DDS技术波形发生器的实验教学研究与实施

Study and Practice on Experiment Teaching Based on DDS Design

通过分析研究直接数字频率合成技术DDS波形发生器的原理与实现,给出了教学实施的具体内容和参考方案。通过部分重难点功能模块设计的启发引导,在加强了学生对问题深入理解的同时,增加了学生的探索与创新能力。使DDS波形发生器的教学实施具有启发性、设计性、开放性、探索性等特点。

In this paper, a new teaching scheme on Direct Digital Frequency Synthesis （DDS） and its content are presented for reference, based on the analysis on the principle and implementation of DDS, The core module design is introduced, which helps the students better understand design process, as well as promotes the students＇ innovative ability. Therefore, the teaching is inspiring, heuristic and explorative.
