Wavelet analysis, an exciting new theory on the forefront of scientific thought, is a unifying concept that interprets a large body of scientific research. Everywhere around us are signals that can be analyzed. For example, there are Seismic tremors, human speech, engine vibrations, medical images, financial data, music, and many other types of signals. Wavelet analysis is a new and promising set of tools and techniques for analyzing these signals. This paper examines the use of wavelets for signal analysis.
