nyquist sampling theorem

常見例句

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，采樣率必須是被測信號(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.
采樣定理表明，如果奈奎斯特頻率大于樣本的帶寬或樣本成分的最高頻率，系統(tǒng)的采樣失真可以避免。
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.
按照耐奎斯特空間采樣定理，陣元間距超過半波長將會(huì)帶來方位估計(jì)的周期性模糊。
