poly2lsf() - Signal Processing

lsf = poly2lsf(a) returns
a vector, lsf, of line spectral frequencies from
a vector, a, of prediction filter coefficients.

Syntax

lsf = poly2lsf(a)

Example

Generate Line Spectral FrequenciesOpen This Example
Given a vector, a, of prediction filter coefficients, generate the corresponding line spectral frequencies.
a = [1.0000  0.6149  0.9899  0.0000  0.0031 -0.0082];
lsf = poly2lsf(a)

lsf =

    0.7842
    1.5605
    1.8776
    1.8984
    2.3593
