摘要
针对谐波分析仪采用FFT算法计算速度虽快但不能保证精度的缺点,提出了一种改进的傅里叶算法,该算法计算速度虽慢,但精度较高,能有效地克服非周期分量对谐波测量的影响。
The measureing error of the harmonic analyzer using FFT algorithm is studied and a new kind of improved Fourier algorithm is suggested. The result of simulation show that the algorithm will not be affected by aperiodic component and posses higher accuracy.
