ABSTRACT
Wavelets have become a necessary mathematical tool in many investigations. They are used in those cases when the result of the analysis of a particular
signal
* should contain not only the list of its typical frequencies (scales) but also knowledge of the definite local coordinates where these properties are important. Thus, analysis and processing of different classes of nonstationary (in time) or inhomogeneous (in space) signals is the main field of applications of wavelet analysis.
