techniques works??(at the bit level).
it will be better if you provide an example which will make the idea
clear.

If you can handle a 200k PDF file, I can send you the handouts I prepared
for a multiplexing class a few years ago. It includes the A-law and u-law
curves, bit and byte values, etc. Although the material is just a
discussion aid, it does give good clues to what you seek.
