Basic theory of spectrum analysis and FastFourierTransform (FFT) algorithm are briefly introduced.
简介了频谱分析的基础理论和快速傅利叶变换(FFT)算法。

The fastFouriertransform (FFT) will bring on higher error under nonsynchronous sampling and truncated non-integral period, thus more accurate interharmonic parameter values cannot be obtained.
