Unformatted text preview: difference equation y[n] – y[n1] – y[n2] = x[n] (1) Assume that the input for the system is x[n] = ± [n] and that the initial conditions are y[1] = y[2] = 0. What will be the output of the system? & ∞ =+ = ] [ ) ( n n z n x x X ) ( ] [ z X n x u + → ← ) ( ] 1 [ ] [ 1 1 z X z z m k x m n x m m k k u += ++→ ←& , ] [ ≥ = n p n x n d. Apply the unilateral Z transform to Eq. (1) and use the linearity property, the timeshifting property and the initial condition in order to find Y + (z). e. Find an explicit expression for y[n] by calculating the inverse unilateral ztransform of Y + (z)....
