rc2is

Conversion of reflection coefficients into arcsine parameters.

Library

EngeeDSP

Syntax

isin = rc2is(k) — returns the arcsin parameters isin obtained from reflection coefficients k.

# k — reflection coefficients

+ vector | the matrix

Details

A list of reflection coefficients specified as a vector or matrix.

# isin — arcsin parameters

+ vector | the matrix

Details

The arcsin parameters returned as a vector or matrix, where isin = (2/π) * asin(k).

Details

Set the vector k the reflection coefficients and determine the corresponding parameters of the arcsine.
