摘　　要：本文介绍了声音节目中造成非线性幅度失真的原因及其去除方法,提出了信号产生模型和失真过程模型以及非线性系统在去失真过程中的应用,并给出了模型的参数估计的方法,最后给出了一个去失真过程的实例。This paper gives an introduce to the mechanisms by which the non-linear distortion can occur in audio programs and the methods of eliminating it, discusses the model of the signal occurred and the model of the distortion process. Also this paper discusses the applications of the non-linear system in distortion-eliminating process and the methods of parameter estimation in the models. In addition, this paper gives an example of distortion eliminating.
