A filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.

WebAug 1, 2006 · Such a medium exhibits significant attenuation due to wave-induced fluid flow across the interface between inclusion and background. For the representative element containing two layers (one of them representing inclusion), we show that overall wave attenuation is governed by the superposition of two coupled fluid-diffusion processes.
