Thanks in advance Srikanta Agrawala



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.
