The support of daubechies
WebOct 16, 1998 · Daubechies wavelets in quality of electrical power. Abstract: Wavelet analysis is a new method for electrical power quality analysis. A brief theoretical background on the wavelet theory and suggestions of some applications in the area of power quality are presented. Investigations on the use of some Daubechies wavelets, namely Daub4, … WebThe Daubechies wavelets, based on the work of Ingrid Daubechies, are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function (called the father wavelet) which generates an orthogonal ...
