2 Filter Structures supported by ASPT

This section is a brief review of the digital filter structures supported by the Adaptive Signal Processing Toolbox. Each section describes the equations involved in calculating the filter output and gives specific information on how the filter structure can be used as an adaptive filter. Links to ASPT functions implementing adaptive algorithms based on each structure to adjust the filter coefficients are also given. The transversal filter structure is considered in Section 2.2.1, the linear combiner filters structure is considered in Section 2.2.2, the recursive filter structure in Section 2.2.3, the lattice filter structure in Section 2.2.4, and finally the nonlinear transversal filters in Section 2.2.5.
