Wavlet Tutorials

Wavlet means a little or a small wave localized in a certain time. These wavlets are used in transformation of a signal from time domain to time-scale (frequency) representation of a signal. Wavlet transform is a tool used to analyze raw signals and have many applications in DSP.

Here are links to lectures introducing wavlet transform from the university of St. Thomas :
