nyquist sampling theorem

基本解释

According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
根据Nyquist定理，采样率必须是被测信号最高频率分量的两倍以上。
The sampling theorem shows that aliasing can be avoided if the Nyquist frequency is greater than the bandwidth, or maximum component frequency, of the signal being sampled.
采样定理表明，如果奈奎斯特频率大于样本的带宽或样本成分的最高频率，系统的采样失真可以避免。
Extending the uniform intersensor spacing beyond a half-wavelength would lead to a set of cyclically ambiguous direction-of-arrival estimates, in accordance with the spatial Nyquist sampling theorem.
按照耐奎斯特空间采样定理，阵元间距超过半波长将会带来方位估计的周期性模糊。
