Abstract

BOLZAN, Maurício José Alves. Wavelet transform: a necessity. Rev. Bras. Ensino Fís. [online]. 2006, vol.28, n.4, pp. 563-567. ISSN 1806-1117.  http://dx.doi.org/10.1590/S1806-11172006000400019.

The aim of this work is to show, within an historical context, the need of the wavelet transform use. Simple computational experiments to explain the origin of this mathematical tool are used. A home-page is available for download of the software program.
