problems in G 723.1

Started by shanky_b_2001 May 5, 2002
Hi all,
I am facing few problems while debugging the Standard C code of
G 723.1 for TI processors.


1) Even after disabling the High pass filter why the Rem_DC function
downscales the samples????

2) Why the LPC filter we use is of 10th order only??? I am unable to
find reasons behind it..

3) what is a codebook??

4) what algo we use to convert LPC coifficients to LSP coifficient..

i'll b obligated if someone will help me out..
