| Abstract: | This article introduces a kind of fast algorithm used half-cycleFourier algorithm to eliminate decreasing exponential DC component. Its data window is a half cycle of this algorithm is much better than that from the half-cycle Fourier algorithm. With the algorithm the influence of an exponential DC component on the fundamental wave component of random decreasing time consent τ can be completely eliminated. A lot of simulations proves that the new algorithm has advantages of efficiency to decrease the exponential DC component、simple calculating、fast velocity. All of the above shows that the algorithm presented in this paper are of value in practical. |
