| 摘 要： | 卷积同态系统可以将卷积组合的信号转化成倒频域以内相加组合的信号，本文正是利用了卷积同态系统的这一特点进行信号的恢复的。本文首先简单地介绍了卷积同态系统的组成和信号恢复的方法，接下来给出了用螺母、小球以及力锤进行的试验的结果，各种试验条件下的信号恢复的结果是令人满意的。最后给以后的研究方向作出了一个展望。

| Abstract: | The homomorphic signal processing system can transform a convoluted signal into added signal in cepstrum domain.In the paper,the original impact signal recovery by use of homomorphic signal processing system is concerned.The impact signal of falling nut to a metal plate is recovered.In order to compare the recovery result with the reality,the impact signals of a falling ball and a hammer are recovered.The result shows that the method offered in the paper is effective and the application of the method in LPMS is prospected. |
