Orthogonal and Biorthogonal Filter Banks

Daubechies’ extremal-phase wavelets, Daubechies’ least-asymmetric wavelets, Fejer-Korovkin filters, coiflets, biorthogonal spline filters

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.
