dfilt.latticemamin

Discrete-time, lattice, moving-average filter

Syntax

Hd = dfilt.latticemamin(k)
Hd = dfilt.latticemamin

Description

Hd = dfilt.latticemamin(k) returns a discrete-time, lattice, moving-average, minimum phase, filter, Hd, with lattice coefficients k.

Note

If the k coefficients define a minimum phase filter, the resulting filter in this structure is minimum phase. If your coefficients do not define a minimum phase filter, placing them in this structure does not produce a minimum phase filter.

Hd = dfilt.latticemamin returns a default discrete-time, lattice, moving-average, minimum phase, filter, Hd, with k=[ ]. This filter passes the input through to the output unchanged.

The resulting filter states column vector is

[z(1)z(2)z(3)]

Examples

Form a third-order lattice, moving-average, minimum phase, filter structure for a dfilt object, Hd, using the following lattice coefficients.

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