通过广义叠加的概念，一些非线性滤波问题的方法已被证明是有用的。本文研究了这种方法的非线性滤波信号，可以表示为产品或作为卷积的组件。文中介绍了该方法在音频动态范围压缩与扩展、图像增强与带宽降低、回声消除、语音波形处理等方面的应用。
An approach to some nonlinear filtering problems through a generalized notion of superposition has proven useful In this paper this approach is investigated for the nonlinear filtering of signals which can be expressed as products or as convolutions of components. The applications of this approach in audio dynamic range compression and expansion, image enhancement with applications to bandwidth reduction, echo removal, and speech waveform processing are presented.
