related to the wavelet theory

Started by adrian September 15, 2008
      Hi,

I am new to everything related to the wavelet theory, but i find it very
interesting and would like to know more about it. I have some questions and
was hoping someone could help me.

1. What is the number of zero moments of a Haar mother wavelet? Is the
answer related to the fact that the Haar function is not continiously
diferentiable?
2. Why a RI spline wavelet is superiour to a Spline wavelet in the
applications concerning the musical signals? For that kind of noise this
superiority could be highlighted?

In English it's a little bit difficult to express myself so i will ask the
same questions in French,is i didnt make myself understood:
1.Quel est le nombre de moments nuls de l’ondelette mère de Haar ?
2.Pourquoi l’ondelette RI-spline est supérieure à une ondelette spline
dans les applications de débruitage des signaux musicaux et pour quel type
de bruit on peut mettre en évidence cette supériorité ? 

                         thank you
