where Y(x) represents the actual output from prediction filtering. Consider the discrete form of equation (G-32), with F(x) represented by the m-length complex array F : (F0, F1, F2, …, Fm−1), P(x, ω) represented by the n-length complex array P : (P0, P1, P2, …, Pn−1), and Y(x) represented by the (m + n − 1)-length complex array Y : (Y0, Y1, Y2, …, Ym+n−1). Equation (G-32) can then be expressed in matrix form
