摘　　要：周期信号傅里叶级数分析教学中,内容繁多,画图困难,应用Matlab GUI设计了两个演示系统。通过GUI界面,分析了八种对称性周期性信号与傅里叶级数系数关系以及典型周期矩形信号的时-频域特性,以交互的方式实现周期信号傅里叶级数分析动态演示仿真。系统将抽象的信号频谱内容直观化、可视化,激发学生学习兴趣,提高教学质量和效率。In the teaching of Fourier series analysis of periodic signals,there are many contents and it is difficult to draw pictures.Two demonstration systems are designed by Matlab GUI.The relationship between eight symmetrical periodic signals and Fourier series coefficients and the time-frequency characteristics of typical periodic rectangular signals are analyzed through GUI inter⁃face.The dynamic demonstration simulation of Fourier series analysis of periodic signals is implemented in an interactive way.The abstract content is visualized and visualized.It stimulates students'interest in learning and improves the quality and efficiency of teaching.
