Shannon sampling theory
Webb16 sep. 2024 · Nyquist–Shannon sampling theorem 总结自: 采样定理 Nyquist–Shannon (奈奎斯特-香农)采样定理 是数字信号处理领域中的一个定理，它是连接连续时间信号和离散时间信号的基本桥梁。 定理内容 :如果一个系统以超过信号最高频率至少两倍的速率对模拟信号进行均匀采样，那么原始模拟信号就能从采样产生的离散值中完全恢复。 为了防止 … Webbpossible and that Shannon’s sampling theory, in its modern and extended versions, can perfectly handle such “nonideal” situations. Ten to 15 years ago, the subject of sampling had reached what seemed to be a very mature state [26], [62]. The re-search in this area had become very mathematically oriented,

WebbThe original proof presented by Shannon is elegant and quite brief, but it offers less intuitive insight into the subtleties of aliasing, both unintentional and intentional. Quoting Shannon's original paper, which uses ''f'' for the function, ''F'' for the spectrum, and ''W'' for the bandwidth limit:Let F ( ω) be the spectrum of f ( t). Webb30 maj 2008 · Shannon wavelets are studied together with their differential properties (known as connection coefficients). It is shown that the Shannon sampling theorem can be considered in a more general approach suitable for analyzing functions ranging in multifrequency bands. This generalization coincides with the Shannon wavelet …
