周期冲激函数与黎曼引理

Period impulse function and Riemann lemma

证明了周期冲激函数展开所得到的傅里叶级数收敛于冲激函数 ,冲激函数不满足黎曼引理 ,因此由黎曼引理导出的傅里叶级数的性质不适合于周期冲激函数 .

In the paper,it is proved that period impulse function is divided into Fourier series is convergent.As Riemann lemma do not adapt to impulse function,the quality that Riemann lemma guides Fourier series is not usedperiod impulse function.The quality of Fourier series coefficient that Riemann lemma guides is revised.
