nyquist sampling theorem
常见例句
- According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
根據Nyquist定理,採樣率必須是被測信號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,系統的採樣失真可以避免。 - 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樣定理,陣元間距超過半波長將會帶來方位估計的周期性模糊。 返回 nyquist sampling theorem
