duration sampling of components states 元件状态持续时间抽样
Rational arrangement and selection of sampling duration are discussed.
同时，对采样时段的合理安排做了初步探讨。
Anew approach, named Modified Fast Fourier Transform (MFFT), is proposed to analyze the components of a periodic signal when sampling duration is not equal to an integer multiple of the fundamentals.
提出了一种改进的快速付立叶变换(MFFT)的计算方法，在采样的持续时间不是信号周期整数倍的条件下，能够准确地提供此信号中各周期分量的特性。
The FDA Guide suggests that the sampling scheme and duration should be the same as for phase one.
FDA指南建议取样计划和持续时间和第一阶段一样。
