Biorthogonal :: Wavelets: A New Tool for Signal Analysis (Wavelet Toolbox)

Wavelet Toolbox

Biorthogonal

This family of wavelets exhibits the property of linear phase, which is needed for signal and image reconstruction. By using two wavelets, one for decomposition (on the left side) and the other for reconstruction (on the right side) instead of the same single one, interesting properties are derived.

You can obtain a survey of the main properties of this family by typing waveinfo('bior') from the MATLAB command line. See Biorthogonal Wavelet Pairs: biorNr.Nd for more detail.
