[波粒二象性,?,量子] 三张螺旋桨飞机飞行的照片

                                               

螺旋桨飞机: propeller aircraft

波粒二象性: wave-particle duality

采样定理: Whittaker-Kotel'nikov-Shannon sampling theorem, WKS-sampling theorem, WKS-theorem

                                          

                                                     

一、三张螺旋桨飞机飞行的照片

二、采样定理(WKS-theorem)的发展时间节点

Whittaker-Kotel'nikov-Shannon (WKS) sampling theorem

   (1)1915年,E. T. Whittaker (Edmund Taylor Whittaker) 发表的统计理论。

   (2)采样定理是1928年由美国电信工程师 H.奈奎斯特 Nyquist (Harry Nyquist) 首先提出来的,因此称为奈奎斯特采样定理。

   (3)1933年由苏联工程师科捷利尼科夫 Kotelnikov 首次用公式严格地表述这一定理,因此在苏联文献中称为科捷利尼科夫采样定理。

  

   (4)1948年信息论的创始人 C.E.香农 (Claude Elwood Shannon) 对这一定理加以明确地说明并正式作为定理引用,因此在许多文献中又称为香农采样定理。(直到 1949 年,克劳德·香农才重新发现了采样定理。)

   由于 1915~1933年 Whittaker、Nyquist、Kotelnikov 的工作没有传播开来,才导致 1949 年 Shannon 重新发现了采样定理。
