Hi,

I'm starting on studying the DSP56000 for an exam at the Eindhoven University
of Technology (the Netherlands). I ran into the terms 'MU-law' and 'A-law'.
The X data ROM in the DSP56000 seems to be factory programmed with these
tables. 

Could anybody tell me in what way these tables can be used ? I have the idea
that the tables have something to do with (data)compression, but I might be
wrong...
