Owning Class: linear systems

Requires: MathScript RT Module

Syntax

k = tf_to_lattice(b)

k = tf_to_lattice(b, option)

[k, v] = tf_to_lattice(b, a)

Legacy Name: tf2latc

Description

Converts a transfer function to a lattice filter.

Examples

Inputs

Name Description
b Specifies the forward filter coefficients. b is a real vector.
a Specifies the backward filter coefficients. a is a real vector.
option Specifies the type of filter. option is a string that accepts the following values:

'min' Minimum-phase FIR filter.
'max' Maximum-phase FIR filter.

Outputs

Name Description
k Returns the lattice reflection coefficients.
v Returns the lattice ladder coefficients.
