| Abstract: | This article make use of MATLAB to emulate traditional full-cycle Fourier algorithm and two kinds of improved Fourier algorithm,then analyze the spectrum picture of these algorithm.The result demonstrate that the improved Fourier algorithm can filter decaying DC component effectively.We can obtain the magnitude of fundamental wave and harmonic wave more accurate than traditional full-cycle Fourier algorithm. |
