Fast Fourier transform (FFT) is the main algorithm for harmonic analysis in electric power system, but when there is the decaying DC component in input signal, FFT algorithm will have higher error.
快速傅里叶变换(FFT)是电力系统进行谐波分析的主要算法，但当输入信号中含有衰减直流分量时，FFT算法会产生较大的误差。
Relative to the funds we have, I will have a higher tracking error and more active money, and probably more in medium and small sized stocks.
与我们的基金有关的，我会允许高一些的跟踪误差和更多的流动货币，可能更多的在中小规模股票。
