nyquist sampling theorem

基本解釋

According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
根據(jù)Nyquist定理，採(cǎi)樣率必須是被測(cè)信號(hào)最高頻率分量的兩倍以上。
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.
採(cǎi)樣定理表明，如果奈奎斯特頻率大於樣本的帶寬或樣本成分的最高頻率，系統(tǒng)的採(cǎi)樣失真可以避免。
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.
按照耐奎斯特空間採(cǎi)樣定理，陣元間距超過(guò)半波長(zhǎng)將會(huì)帶來(lái)方位估計(jì)的周期性模糊。
