Over the last two decades, wavelets have gained a lot of popularity and become a standard tool for many disciplines. Despite all the attention, it can be difficult to obtain filter coefficients for even the most commonly used wavelets. This document is a reference, listing filters for wavelets in the Daubechies, symlets, Coiflets, and biorthogonal spline families and the CDF 9/7 wavelet. For some wavelets, a filter sequence for lifting scheme implementation is also provided.

Typo fixed, (z+1) should be (z+z^-1) in CDF 4.4 --- thank you Ryszard Maciol
