Summary:

A simple analytic design procedure for Lattice Wave Digital Filters (LWDFs) is presented with an approximate linear phase. The design is started by replacing one of the two all-pass filter branches in LWDF with a pure delay and terminated by some analytic design formulas. Using Matlab 7.4, several design examples of the odd order type utilizing such procedure are given for verifications.
