RESUMO
Filter banks and wavelets are tools of Engineering, dened over complex elds, with many applications. This dissertation introduces the theory of lter banks and wavelets dened over nite elds, over cyclical and noncyclical structures. The problem of dening two-channel lter banks and wavelet decompositions over elds of characteristic two was solved, thereby providing a new perfect reconstruction condition for these structures. Applications, in the areas of data security, error correcting codes, multiplex and spread spectrum, of these new tools are suggested
