dfilt.latticeallpass

Construct a discrete-time, lattice allpass filter object

Syntax

• Hd = dfilt.latticeallpass(k)
  Hd = dfilt.latticeallpass
  

Description

Hd = dfilt.latticeallpass(k) returns a discrete-time, lattice allpass filter object, Hd, with lattice coefficients, k.

Hd = dfilt.latticeallpass returns a default, discrete-time, lattice allpass filter object, Hd, with k=[ ]. This filter passes the input through to the output unchanged.

Examples

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

• k = [.66 .7 .44];
  Hd = dfilt.latticeallpass(k)
  Hd =
       FilterStructure: 'Lattice allpass'
               Lattice: [0.6600 0.7000 0.4400]
