Resumen
Digital signal processing (DSP) aims to extract specific information from digital signals.
Digital signals are, by definition, physical quantities represented by a sequence of
discrete values and from these sequences it is possible to extract and analyze the desired
information. The unevenly sampled data can not be properly analyzed using standard
techniques of digital signal processing. This work aimed to adapt a technique of DSP,
the multiresolution analysis, to analyze unevenly smapled data, to aid the studies in the
CoRoT laboratory at UFRN. The process is based on re-indexing the wavelet transform to
handle unevenly sampled data properly. The was efective presenting satisfactory results
