Orthogonal wavelet filter banks generate a single scaling function and wavelet, whereas biorthogonal wavelet filters generate one scaling function and wavelet for decomposition, and another pair for reconstruction. Daubechies’ least-asymmetric filters have the most linear phase response of the orthogonal filters. If you require linear phase, use biorthogonal filters.

The type of wavelet analysis best suited for your work depends on what you want to do with the data.
Understand how to reconstruct signals from wavelet transformed data.
This example shows how to add an orthogonal quadrature mirror filter (QMF) pair and biorthogonal wavelet filter quadruple to the Wavelet Toolbox™.
Show how the number of vanishing moments affects smoothness biorthogonal filter pair.
