waveinfo("db")
Information on Daubechies wavelets. Daubechies Wavelets General characteristics: Compactly supported wavelets with extremal phase and highest number of vanishing moments for a given support width. Associated scaling filters are minimum-phase filters. Family Daubechies Short name db Order N N a positive integer from 1 to 45. Examples db1 or haar, db4, db15 Orthogonal yes Biorthogonal yes Compact support yes DWT possible CWT possible Support width 2N-1 Filters length 2N Regularity about 0.2 N for large N Symmetry far from Number of vanishing moments for psi N Reference: I.
