Mu-Law Expander - Implement µ-law expander for source coding

Library

Source Coding

Description

The Mu-Law Expander block recovers data that the Mu-Law Compressor block compressed. The formula for the µ-law expander, shown below, is the inverse of the compressor function.

The input can have any shape or frame status. This block processes each vector element independently.

Dialog Box

mu value

The µ-law parameter of the compressor.
