摘要
针对全周傅立叶变换快速算法在处理含有衰减直流分量的周期信号时会产生误差的问题,分析衰减直流分量在傅立叶快速算法结果的变化规律,对计算结果进行修正,从而得到了各周期分量的精确计算结果。通过计算证实,该方法行之有效。
To solve the shortcoming of the fast algorithm of full-wave Fourier transmit （FFT） in the sampling signal, the variation rules of decaying DC component in the results of the fast algotithm of FFT are analyzed, The Solution to the influence is suggested. The result of calculation are modified. The calculation result of every frequency is obtained. The calculation result verifies the validity of the suggseted solution.
