2. Find the region of convergence (if it exists) in the z plane, of the z transform of these signals: (a) x[n] = u[n] + [n] (b) x[n] = u[n] - u[n - 10] (c) x[n] = 4n un + 1] (Hint: Express the time-domain function as the sum of a causal function and an anticausal function, combine the z-transform results over a common denominator, and simplify.) (d) x[n] = 4n u[n - 1] (e) x[n] = 12 (0.85)" cos(2tn/10)...
5. Calculate the z-transform of x[n] = 0.2"u[n – 3], and determine its region of convergence.
4. Find the z-transform (if it exists) and the corresponding region of convergence for each of the following signals. To the extent possible, use the properties of the z-transform to enable the re-use of standard results and reduce calculations. Simplify your expressions. (Recall that for real-valued signals, the transform should only have real-valued coefficients.) (a) z[n] = (1)(n-1) sin(竽幔)u[n-2] (b) x[n-2"u[n] + 0.5"u[n-2] (d)-[n] = n(j)nuln-3]
