摘要
介绍了“周期信号频谱分析演示ＣＡＩ软件”的设计思路和编程方法。该软件采用辛甫生积分法计算周期信号的傅里叶系数，并由此给出相应的双边频谱图、傅里叶级数展开式及傅里叶系数表达式。
This paper introduces the designing way and the programming methods of the CAI software for periodic signal spectrum analysis and demo .The CAI software calculates fourier coefficients of periodic signal with the help of xinposheng integral method and gives out bilateral spectrum graphs and fourier series formula and fourier coefficient formulas of periodic signal .The software applied can be to the spectrum analysis demo of periodic signal related with content of courses.
