Abstract

In this paper we present the practical significance of Daubechies wavelets with real data. The first section includes the theoretical background based on the Fast Daubechies wavelet transform algorithm. The second section comprises the algorithm implementing in Microsoft Excel with VBA and explains the significance of the wavelet coefficients obtained in the study of semiweekly measurements of temperature at Cluj-Napoca location.
