dfilt.latticearma

Discrete-time, lattice, autoregressive, moving-average filter

Syntax

Hd = dfilt.latticearma(k,v)
Hd = dfilt.latticearma

Description

Hd = dfilt.latticearma(k,v) returns a discrete-time, lattice autoregressive, moving-average filter, Hd, with lattice coefficients, k and ladder coefficients v.

Hd = dfilt.latticearma returns a default, discrete-time, lattice autoregressive, moving-average filter, Hd, with k=[ ] and v=1. This filter passes the input through to the output unchanged.

The resulting filter states column vector is

Examples

Form a third-order lattice autoregressive, moving-average filter structure for a dfilt object, Hd, using the following lattice coefficients:

k = [.66 .7 .44];
Hd = dfilt.latticearma(k)

Hd =

                    Average (ARMA)'
          Lattice: [0.6600 0.7000 0.4400]
           Ladder: 1
