Abstract
The properties of sinc approximations are considered. Previously used classical sinc-approximations provide poor approximation quality, while a new operator generalizing sinc approximations yields better results. The numerical implementation of an experiment is presented in plots.

摘要
考虑了 sinc 近似的性质。以前使用的经典 sinc 近似提供了较差的近似质量,而推广 sinc 近似的新运算符会产生更好的结果。实验的数值实现以图表形式呈现。
