I want to learn how to compute linear coefficient, but to be honest - I can't. I know how to use them if i have it and why I want them.
Suppose this toy example:
A signal $x=[-1, -2, 0, 1]$
According to matlab function
lpc(X,p) if I want to compute the 2th order coefficients of this signal the result is $a = [1.0, -0.50, 0.50]$ and $ g=1.0$
I Know how to compute the g using $A(k)$ formula and that $a_0=1$ always, but can someone explain me why $a_1=-0.5, a_2=0.5$ how to compute them without using matlab or any other software.
P.S It there any method which allow me using $A(k)$ to compute directly the coefficients?
