The main m-file to be executed is myLPC.m file. The file that contains all calculations is lpc_01.m file, that is a function which returns reconstructed speech signal with LPC-16 coding.
Observing Spectrogram of both signals is very instructive and shows that Reconstructed signal from LPC coding has some periodic (with respect to w) signals appearing in it s Spectrogram.
