Implement µ-law compressor for source coding
The Mu-Law Compressor block implements a µ-law compressor for the input signal. The formula for the µ-law compressor is
where µ is the µ-law parameter of the compressor, V is the peak
magnitude of x, log is the natural logarithm, and sgn is the signum
sign in MATLAB®).
The input can have any shape or frame status. This block processes each vector element independently.
The µ-law parameter of the compressor.
The peak value of the input signal. This is also the peak value of the output.
