problems in G 723.1 - shanky_b_2001 - May 5 5:57:00 2002

Hi all, I am facing few problems while debugging the Standard C code of G 723.1 for TI processors. Problems: 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.. tahnks sachin |
