最小相位信号可由其傅氏变换的幅度或相位来恢复。现已有一些恢复算法。本文根据复倒谱原理提出一种新算法,并给出数值计算例,具体说明这种方法的优越性。
The minimum phase signal can be recovered by the magnitude or phase of its Fourier transform. There are some recovery algorithms. In this paper, we propose a new algorithm based on the principle of complex cepstrum, and give numerical examples to illustrate the superiority of this method.
