摘要
本文对用窗函数截取时域和空域信号的影响进行了分析,并设计了仿真实验和实测数据的处理实验来辅助基础理论教学,将规律和结论直观地呈现给学生。通过课程内容的对比和类比、基础理论与工程研究的结合等方式,可以激发学生的学习兴趣和学习动力,培养学生从事科学研究的方法和技能。教学实践证明,该课程设计的教学效果良好。
The window adding problem in time domain and spatial domain signal processing is discussed using the methods of comparison and analogy,and the simulation experiments and signal processing experiments are designed to aid basic theory teaching and show conclusions distinctly in this paper.The students′ learning interest and learning motivation are stimulated by comparison and analogy of the basic course contents.Scientific research methods and skills are trained utilizing combination of basic theory and engineering research.Proven by the teaching practice,this instructional design is resultful.
