摘要
针对“数字信号处理”课程概念抽象、公式繁琐的特点,利用MATLAB App Designer控件多、界面友好、交互性强等特点设计了一款教学辅助系统。包含了数字信号处理课程内容中的常见信号及其运算、傅里叶变换及分析、滤波器设计、综合应用等方面。通过输入参数或修改参数,就能显示相应的响应结果,从而将数字信号处理抽象的数学运算,变成直观的、可视过程,有利于学生增强对理论的理解。设计的程序可添加在MATLAB App中随时调用,也可形成脱离MATLAB环境的可执行文件,经过2年在教学演示、实验辅助等方面的应用,取得了良好的效果。
In view of the abstract concept and complicated formulas in the course of digital signal processing, this paper designs a teaching assistant system by using the MATLAB App Designer which has a large set of interactive UI components. The App designs common signals and their operations, Fourier transformation and analysis, filter design, comprehensive application etc. Through inputting different parameters, the corresponding response results can display, so that students can intuitively understand the process of digital signal processing, enhance their understanding of the theory. This design can be packaged into the MATLAB installer files directly, and created as a standalone desktop or Web App. After 2 years of application, the system has achieved good results in the experiment demonstration and experimental assistance.
