Hi,
I have a project called "pitch detection using LPC parameters with MATLAB code".The input voice is lowpass filtered a cut off frequency of about 900Hz and then the sampling rate (nominally 10kHz) is reduced to 2kHz by a decimation process.The decimated output is than analyzed using the autocorrelation method with a value of p=4 for the filter order.

İf you can help me, I will be gratefully.
Thanks already....:)
