By the decomposition of the minimum and maximum phase components, the group of wavelets with the same amplitude spectrum and different phase spectrum could be found in cepstrum domain.

同态反褶积是一种利用复赛谱技术提取子波和进行子波反褶积的方法，它要求在频率域将子波相位正确地展开计算。

Among the methods for estimating the minimum phase wavelet from its amplitude spectrum, methods of Hilbert-transform, of homomorphy, of zero-phase wavelet and of relaxation-iteration are analysed.

根据子波振幅谱估算最小相位子波已有多种方法，本文对用希尔伯特变换法、同态法、零相位子波法、松弛迭代法等估算的最小相位子波，进行了详细的分析。
