Wavelets - the Idiots Guide
October 1997 - Gavin Tabor
This article gives a brief description of what Wavelets are. It doesn't explain the theory of wavelets, but gives some examples of signal analysis.
The Wavelet Tutorial
January 2001 - Robi Polikar
This article gives a very good explanation of what Wavelet Transforms are. It also explains the algorithm for the Discrete Wavelet Transform. To introduce the concept of WT the Fourier Transform is explained as well.
Wavelet Cascade Applet
October 1997 - Wim Sveldens
This applet together with mathematical description show how different scale functions wavelet functions are built. These functions are used in the wavelet transform.
This is a chapter from an unknown book is an excellent resource for Wavelet interested people. It explains the mathematics behind the Wavelet Transform in detail.
The Discreet Wavelet Transform
May, 2002 - Andreas Jönsson
Shows how the discret wavelet transform works. Complete with sample demo and source code.
