Implement A-law expander for source coding
The A-Law Expander block recovers data that the A-Law Compressor block compressed. The formula for the A-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.
The A-law parameter of the compressor.
The peak value of the input signal. This is also the peak value of the output signal.
Match these parameters to the ones in the corresponding A-Law Compressor block.
