As discussed in Section 11.7.3, Burg (1975) proposed computing the k parameters so as to minimize the sum of the forward and backward prediction errors at the ith stage of the lattice filter; i.e.,
where the sum is over the fixed interval i ≤ n ≤ M.
a) Substitute the lattice filter signals into (P11.30-1) and show that the value of ki that minimizes B(i) is
(b) Prove that − 1 < k B i < 1.
Hint: Consider the expression where x[n] and y[n] are two distinct sequences.
(c) Given a set of Burg coefficients how would you obtain the coefficients of the corresponding prediction error filter A(p)(z)?
