For a minimum or maximum phase finite impulse response (FIR) filter, you can implement a lattice moving average (MA) filter structure. The following figure represents the lattice MA filter structure for a minimum phase filter. M is the filter order. Refer to the Understanding Filter Structure Graphs topic for information that helps you read and understand a filter structure graph.

The following figure represents the lattice MA filter structure for a maximum phase filter.

For both the minimum and maximum phase type, the total number of the lattice reflection coefficients k is M. The total number of multipliers is 2M.
