摘要
在全波傅氏算法的基础上提出了一种新的滤波算法，该算法适用于输入信号中除直流分量和整数次谐波分量外，还包含衰减直流分量的情况，其能弥补衰减直流分量对全波傅氏算法的影响而求得精确的基波分量和谐波分量。算例表明，该算法具有计算精度高。
This paper presents a novel filtering algorithm based on all wave Fourier algorithm. The novel algorithm can be used when sampling signals include decaying DC component and integer harmonic components. It can obtain precise fundamental and harmonic components. Numerical case indicates that the novel algorithm presented in this paper has higher computation precision and the algorithm is simple.
