Find the z-transform of x(n)=(n-1)(0.3)(n-3)cos(π(n-1)/4)u(n-2). (Find the ROC also).

8) Determine the z-transform of the difference equation shown below. Do not simplify or solve for anything further. Just determine the z-transform. Assume that: • y(−1) = 10, y(−2) = 20 n • x(n) = (-)" u(n) y(n) + 1½y(n y(n)+y(n-2) = 8 x(n)

Find Z-transforms and corresponding regions of convergence for the following signals:

Home Work Find the Z- Transform and mention the Region of Convergence (ROC) for the following discrete time sequences. 1. x (n) = 8(n-2) 2. x (n) = 8(n)
