The phase of the Daubechies filters
Djalil Kateb, Pierre Gilles Lemarié–Rieusset · Revista Matemática Iberoamericana · 1997
We give the first term of the asymptotic development for the phase of the N -th (minimum-phased) Daubechies filter as N goes to +\infty . We obtain this result through the description of the complex zeros of the associated polynomial of degree 2N+1 .
