The support of daubechies

WebDaubechies wavelets extends the haar wavelets by using longer filters, that produce smoother scaling functions and wavelets. Furthermore, the larger the size \(p=2k\) of the filter, the higher is the number \(k\) of vanishing moment. A high number of vanishing moments allows to better compress regular parts of the signal. 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.
