Biorthogonal Wavelet Filters Spectral Analysis by Discrete Hyper-wavelet Transforms
Qingyun Zou, Guoqiu Wang · Advances in Mathematics · 2008
Biorthogonal wavelet filters spectrum by discrete hyper-wavelet transforms is bouned.Moreover,we give it a definite bound.Any biorthogonal wavelet filters spectrum can't inAnitely close to a open interval.We find a interval estimation.Thereby,we show any biorthogonal wavelet filters spectrum can't infinitely close to 1.
