                         wavelet functions. This methodology consists in extraction of part 
                         of the energy from large scales (long periods) determined through 
                         of a threshold chosen from the variance analysis performed by 
                         scale. The Morlet wavelet transform was used in order to show that 
                         this procedure removes the energy from long-term periodicities 
                         while preserving all original frequencies. This method is applied
