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.
- A value
The A-law parameter of the compressor.
- Peak signal magnitude
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.
