    Hi,

    1. would any of you guys happen to know where i can get a simple block diagram of the PCM (Pulse Code Modulator) digital encoder/ decoder with a few explaination of the operation of each blocks?

    2. A more moden updated version of PCM is CELP (Code excited linear prediction) just need an article explaining how it works and its uses in mobile phones.

    Thanks, much appreicated.
