| 摘 要： | 著名的Ｗｈｉｔｔａｋｅｒ－Ｋｏｔｅｌ’ｎｉｋｏｖ－Ｓｈａｎｎｏｎ抽样定理在信号分析与图像处理中起着十分重要的作用，多维抽样理论更是如此，讨论了多维抽样的重构，建立了多维非带限信号的抽样级数对其信号近似表示的混叠误差估计，并提出若干有待进一步讨论的问题。

| Abstract: | The wellknown Shannon sampling theorem which plays a basic role in communication, control theory and data processing, states that every bandlimmited signal funtion can be completely reconstructed from its equally spaced sampled values. The aliasing errors for sampling series of multidimensional nonbandlimmited signals are estimated. And same problems which are worth considering are also presented. |
