摘　　要：信号与系统是电子信息类专业承上启下的一门专业基础课。掌握其基本概念和方法,对所有电子信息工程类专业学生都有着非常重要的作用。然而该课程概念抽象,公式繁杂,理论性强,学生难于理解。该文通过对"信号与系统"课程中抽象概念的可视化方法进行探索,应用GUI编程技术设计出图形用户界面,能够将抽象的理论公式和概念更加直观和形象具体地演示出来。该演示系统交互性好,操作简单,直观性强,能够激发学生的学习兴趣,改善教学效果,提高教学质量。Signal and system is an essential professional basic course of electronic information specialty that connects the preced- ing and the following in electronic information technology. Grasp the basic concepts and methods which have a very important role for all electronic information engineering students. However, the concept of the course is abstract, the formula is complex and the theory is profound, so it is too difficult to understand. Through the exploration of the visualization method of abstract concepts in the course, this paper designs a graphical user interface using GUI programming technology, which can demonstrate abstract theoretical formulas and concepts more intuitively and vividly. The demonstration system has the features of good interaction, simple operation and strong intuition. The students＇ interest is greatly stimulated in learning, so that the teaching effect and the teaching quality are highly im- proved.
