linear to mu conv?? - simha j - Jun 20 7:04:00 2002

hi all, I was going through the c-codes for linear pcm to u-law conversion, available on the web. one of the sources use lookup tabel method and another uses direct implementation (without LUT). I tested both by giving 16bit linear value (0X0100), LUT method is giving o/p as 'OXE7' and the another method as '0XCD'. why there is a change in the u-law compressed output?? How to understand this?? Looking forward to your answers... simha |
