傅立叶变换与小波变换的比较教学

Comparing Teaching of Fourier Transform and Wavelets Transform

本文针对小波变换教学中小流变换概念理解困难的问题,提出了一种比较教学方法,通过分析小波变换与傅立叶变换之间的联系,并从四个方面进行对比,清楚地描述了小波变换的本质,从而对加深对小波变换的理解。

Since the concept of wavelets is difficult to understand. This paper gives a comparing teaching method. Through analyzing the relationship between wavelet transform and Fourier transform from four aspects. The essential characters is described. It will enhance to understand the wavelets transform.
