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。

Being able to process every item of data in reasonable time removes the troublesome need for sampling and promotes an investigative approach to data, in contrast to the somewhat static nature of running predetermined reports.

Although there are likely several reasons for this, and the sampling size might not qualify this as a statistically significant result, I would offer that if you approach a game with the idea of how to work around the rules of the game in increase your odds of winning while your opponents are simply following the rules, your chances of winning will dramatically improve.
