维特克—香农抽样定理 (Wittak - Shannon Sampling Theorem)
维特克—香农抽样定理，也被称为奈奎斯特—香农抽样定理，是一项用于数字信号处理领域的重要定理。该定理由维特克和香农于20世纪40年代分别提出，用于描述在信号采样和重建过程中的采样频率要求和重建精度。
该定理指出，为了在数字信号采样过程中能够准确地重建信号，采样频率必须大于等于信号的最高频率的两倍，即采样频率要高于奈奎斯特频率（Nyquist Frequency）。否则，重建的信号会产生混叠现象，导致信息的丢失和失真。
Wittak - Shannon Sampling Theorem (维特克—香农抽样定理)
The Wittak - Shannon Sampling Theorem, also known as the Nyquist–Shannon sampling theorem, is an important theorem in the field of digital signal processing. This theorem was independently proposed by Wittak and Shannon in the 1940s, and it describes the sampling rate requirements and reconstruction accuracy in the process of sampling and reconstructing a signal.
The theorem states that in order to accurately reconstruct a signal during the digital signal sampling process, the sampling frequency must be greater than or equal to twice the maximum frequency of the signal. This means that the sampling frequency should be higher than the Nyquist frequency. Otherwise, the reconstructed signal will suffer from aliasing, resulting in information loss and distortion.
Pronunciation (英文读音)
