由特殊函数表达的快速取样定理

A High Speed Sampling Theorem Expressed by Special Function

对频谱有限函数，本文给出了新的快速收敛的取样定理．根据具体问题，利用卷积的方法还可以调节收敛速度，达到预期的效果，且计算也并不复杂．

おhis paper gives a new sampling theorem with rapid convergence for the bandlimited function. According to the practical problem the convergence rate may be adjusted by using the function convolution. The algorithm of the sampling theorem is not complicated.
