[ TONE Generation ] PCM - ADPCM - Dhiraviam Natarajan - Sep 13 10:57:00 2003

Hi ppl, I working on tone generation for an Access Network ( of a telephone exchange ). Can some one throw light on PCM to ADPCM conversion algorithm , point me some useful web tutorials / links. Can ADPCM samples be generated directly by any means ? Generally, a simple sine function is used to generate tones. Is that always sufficient? Is there any other means to generate tone? I would appreciate any help in this regard. Thanks a lot, in advance. Regards, / D Natarajan. You may be disappointed if you fail BUT you are doomed if you don't try ! Free thyself from the fear of failure |
