摘要
信号与系统因具有概念抽象和理论性强的特点,所以传统割裂介绍知识点的授课模式难以获得理想的教学效果。本文结合笔者在三届本科生中开设的信号与系统课程,就实际教学过程中存在的问题及难点,对六种傅里叶变换之间的相互关系这部分内容的教学方法提出了实践建议和措施。同时,借助思维导图对六种傅里叶变换之间的相互关系进行描绘和梳理,实现进一步提升课程教学质量的目的。
Because in the course of Signals and Systems there are many abstract concepts and theories, the traditional teaching mode of introducing knowledge points separately is difficult to achieve the ideal teaching result.Based on the Signals and Systems course for undergraduates that the authors have taught three times, this paper puts forward practical suggestions and measures for the teaching method of the relationship between the six Fourier transforms in terms of the problems and difficulties in the actual teaching process.At the same time, the relationship between the six Fourier transforms is described and sorted out with the help of mind maps, so as to further improve the quality of course teaching.
