摘要
利用声表面波器件构造了小波变换及重构器件 ,为小波变换及重构器件开辟了一种新的制造途径 .本文主要论述声表面波式小波变换及重构器件的工作原理 ,并对信号源内阻对声表面波器件的影响和声电再生问题提出了解决方法 .
The surface-acoustic-wave elements are firstly used to make the wavelet-transformation and reconstruction element,and a new manufacturing way for the wavelet-transformation and reconstruction element is created.The principle of the wavelet-transformation and reconstruction element is elaborated,and the solutions for the following two problems are put forward:firstly,the effect of the inner impedance of the signal source on the surface-acoustic-wave element;and secondly,the problem of the sound-electricity-reclamation.
