A note on a practical relationship between filter coefficients and scaling and wavelet functions of Discrete Wavelet Transforms

Abstract: In this paper, the relationship between the filter coefficients and the scaling and wavelet functions of the Discrete Wavelet Transform is presented and exemplified from a practical point-of-view. The explanations complement the wavelet theory, that is well documented in the literature, being important for researchers who work with this tool for time–frequency analysis. [Copyright &y& Elsevier]
