Question:
In section 11.2.4 we indicated that the noise-whitening filter Ap(z) for a causal AR(p) process is a forward linear prediction-error filter of order p. Show that the backward linear prediction-error filter of order p is the noise-whitening filter of the corresponding anticausal AR(p) process.
