摘要
为了改进《信号与系统》课程的教学方法,克服硬件实验系统的局限性,利用Matlab图形用户界面(GUI)开发了信号与系统课程综合实验系统。该系统围绕信号处理中的典型问题进行实验建模和仿真,整个系统由实验主界面和单个实验界面组成,每个实验界面可以由用户自行设置和修改实验参数,实现实验结果的动态显示。通过仿真实验,能够促进学生的感性认识,帮助学生对课程所学理论知识和抽象概念的理解,有效提高信号与系统实验教学效果。同时,该实验系统可以弥补实验设备相对不足的缺陷,成为目前基于硬件实验系统的有效补充。
In order to improve the teaching method of the Signals and Systems course,and overcome the limitation of hardware experiment,an integrated experiments system of Signals and Systems course based on MATLAB graphic users＇ interface is designed.The experiment simulation and modeling are performed by thinking about the typical problems in the Signal and System course.The system is composed of the main menu and the subset experimental menus.Users can set and change the parameters of the experimental menu.The experimental results can be displayed immediately at the screen.The system can help the students obtain the perceptual knowledge and understand the theory and concepts,and improve the teaching effects very much.Moreover,the system remedied the insufficient of the experimental equipments.It will become a supplement for the hardware experimental system.
