In the Wavelet Design Express VI, use the Wavelet Type control on the Configure Wavelet Design dialog box to select the wavelet type. You can choose from the following two wavelet types, Orthogonal (default) and Biorthogonal.
The wavelet transform with orthogonal wavelets is energy conserving, meaning that the total energy contained in the resulting coefficients and the energy in the original time samples are the same. This property is helpful for signal and image compression and denoising. But the filters associated with orthogonal wavelets are not linear phase. Linear phase is a helpful property for feature-extraction applications. The filters associated with biorthogonal wavelets can be linear phase.
