dfilt.latticearma

Construct a discrete-time, lattice, autoregressive, moving-average filter object

Syntax

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

Description

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

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

Examples

Specify a third-order lattice autoregressive, moving-average filter structure for a dfilt object, Hd, with the following code:

• k = [.66 .7 .44];
  Hd = dfilt.latticearma(k)
   Hd =
               FilterStructure: 'Lattice ARMA'
                       Lattice: [0.6600 0.7000 0.4400]
                        Ladder: 1
      NumberOfSamplesProcessed: 0
                   ResetStates: 'on'
                        States: [3x1 double]
