Owning Class: modeling and prediction

Requires: MathScript RT Module

Syntax

[k, r0] = ac_to_rc(r)

Legacy Name: ac2rc

Description

Generates a sequence of reflection coefficients from an autocorrelation sequence input. LabVIEW then can use the coefficients in k to design a lattice prediction filter. This filter generates an autocorrelation sequence similar to the original sequence r.

Examples

Inputs

Name Description
r Specifies the autocorrelation sequence. r is a vector.

Outputs

Name Description
k Returns the reflection coefficients. length(k) equals length(r) - 1.
r0 Returns the zero lag of the autocorrelation sequence.

Details

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes
Supported on RT targets Yes
Suitable for bounded execution times on RT Not characterized

Examples

r = [0.5, 0, -1.75, 3, -2];
[k, r0] = ac_to_rc(r)
