摘　　要：周期信号频谱分析是信号与系统课程中的重要内容,连续时间周期信号频谱的分析方法有傅立叶级数分析和傅立叶变换分析,可以通过对周期矩形脉冲信号的频谱分析来说明这两种方法的区别。利用MATLAB软件,结合其图形用户界面接口(GUI),设计具有良好人机交互界面的周期矩形脉冲的频谱分析仿真软件,既可辅助教师进行课堂教学演示,也可供学生进行实验仿真,得出满意的实验结果,进而帮助学生理解周期信号频谱的特点。Periodic signals frequency domain analysis is the important content of the signal and system course. The Fourier series and Fourier transform are the continuous-time periodic signal spectrum analysis methods. Through the periodic rectangular pulse signal spectrum analysis illustrates the difference between the two methods . Using MATLAB software with its graphical user interface （GUI）, Periodic rectangular pulse spectrum analysis simulation software is disigned with a good man-machine interactive interface.h also can assist teachers in classroom teaching presentations, instead of the traditional blackboard teaching to make classroom teaching more vivid and intuitive.
