frequency sampling theorem

常见例句

In the course of the sampling, the sampling theorem is a basic rule and points out the least sampling frequency for reconstructing the signals .
採樣定理是採樣過程中所遵循的基本槼律，它指出了重新恢複連續信號所必需的最低採樣頻率。
Though examples of common signal and sine signal, by the frequency spectrum graph and theoretical analysis, the minimum sample rate of the sampling theorem is made clear.
以一般信號和正弦信號爲例，通過理論分析和頻譜圖示意，對抽樣定理中最低抽樣率的取值進行了明確的說明。
For bandpass signal under digital quadrature sampling, there is spectrum shifting. Although the sampling frequency satisfies the sampling theorem, it may cause spectrum aliasing.
在數字正交採樣中，帶通信號存在頻譜遷移問題，雖然滿足帶通信號的採樣定理，仍可能産生頻譜混曡。
