A Really Friendly Guide to Wavelets
It is well known from Fourier theory that a signal can be expressed as the sum of a, possibly infinite, series of sines and cosines.
This sum is also referred to as a Fourier expansion.
The big disadvantage of a Fourier expansion however is that it has only frequency resolution and no time resolution.
This means that although we might be able to determine all the frequencies present in a signal, we do not know when they are present.

Discovering Wavelets Web Site
Our goal for this site is to make it a center of activity for incorporating wavelets into the undergraduate curriculum.
We believe that wavelets can be accessible to people other than research mathematicians -- that anyone with a background in basic linear algebra (for example, graduate and undergraduate students, and nonspecialists) can learn about and work with wavelets.

The Wavelet Tutorial for Engineers
Part I of this tutorial presents an overview of the basic concepts that are of importance in understanding the wavelet theory.
This part is strictly for those who have no background in signal processing, somehow heard that some wavelet thing or other is the way to go.

A Practical Guide to Wavelet Analysis
Many time series in geophysics exhibit non-stationarity in their statistics.
While the series may contain dominant periodic signals, these signals can vary in both amplitude and frequency over long periods of time.

Software for Fortran, IDL, and Matlab.

Amara's Wavelet Resource Page
This site overviews wavelets, provides summaries and links to wavelet information around the Net, and includes an FAQ-like paper on wavelets.
This is probably THE best resource for wavelets on the Web.
