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:

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.

Refer to the Understanding Filter Structure Graphs section for information that helps you read and understand a filter structure graph.
