试谈“信号与系统”课程理论与实践之结合

"信号与系统"是高校电工程和信息科学类甚至更多专业的一门重要基础课程。为了进一步提高课程质量,当前改革的首要任务是与理论分析密切配合大力加强工程案例的应用,本文给出了大量新颖生动的应用案例,并指出这些案例的选取背景和原则。最后笔者研究了在加强工程应用的同时如何拓展和深化数学工具之应用。

Integration of Theory and Practice in Signals and Systems

Signals and Systems is an important fundamental course for many disciplines such as electronic engineering and information science in colleges and universities. It has a long history and most of its contents are mature now. To further improve the quality of the course,the current priority of the reform is to vigorously strengthen its application of engineering cases in accordance with theoretical analysis. In this paper,numerous vivid application cases are presented with their backgrounds and selection rules. This paper ends with the research in enhancing engineering applications as well as expanding and deepening usage of mathematical tools.
