基本解釋[數(shù)學(xué)]頻率抽樣定理英漢例句雙語例句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(xù)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(wèi)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(jìn)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(shù)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。frequency sampling theorem更多例句詞組短語短語frequency domain sampling theorem 頻率域採樣定理frequency sampling theorem更多詞組專業(yè)釋義數(shù)學(xué)頻率抽樣定理
