lar2rc (Signal Processing Toolbox)

Convert log area ratio parameters to reflection coefficients.

Syntax

k = lar2rc(g)

Description

k = lar2rc(g) returns a vector of reflection coefficients k from a vector of log area ratio parameters g.

Examples

g = [0.6389    4.5989    0.0063    0.0163   -0.0163];
k = lar2rc(g)
k =
    0.3090    0.9801    0.0031    0.0081   -0.0081
