That is, the AR(2) impulse response is a weighted average of two geometric signals with the weights and given above. We want to feed into the causal prediction filter and obtain as output the advanced signal . As we stated above, E(Z) is the ratio of the one-sided Z-transform of the output over the one-sided Z-transform of the input. Of course, we know that the input Z-transform is F(Z). We can obtain symmetry in our expression for E(Z) if we write the input Z-transform F(Z) as
