基于GUI的信号与系统卷积实验设计

Design of Convolution Experimental in Signal and System Based on GUI

针对电气信息类专业基础课《信号与系统》教学中存在的学时少、理论复杂、学生难理解等问题,设计基于Matlab GUI的卷积部分课堂辅助实验。该GUI界面操作简单,形象直观的展示了离散信号和连续信号求卷积的实例。不同采样间隔的连续信号卷积结果对比,进一步加深了同学们对连续信号求卷积理论的理解。实践表明,结合该辅助实验提升教学效果和学生学习的效率。此外,该设计具有推广性,可作为其他教学辅助实验设计的参考。

Aiming at the problems in the teaching of signal and system,an electrical professional basic course,such as less class hours,complicated theory and difficulty in students'understanding,this paper designed a classroom auxiliary experiment of convolution based on Matlab GUI.The GUI interface is simple to operate and visually shows the convolution of discrete signal and continuous signal.The convolution results of continuous signals with different intervals were compared,which further deepened students'understanding of the convolution theory of continuous signals.The practice shows that the teaching effect and students'learning efficiency can be improved by combining this auxiliary experiment.In addition,the design can be extended,and can be used as a reference for the design of teaching assistant experiments in other teaching courses.
