QUESTION 1 Z-transform of any discrete -time signal can be defined using expression below, X(Z) = ∑n=-∞^+∞ x[n]z^-n, By using above Z-transform expression, derive and prove that both discrete-time signal below produces similar X(Z) expression but having different ROC. x1[n] = a^nu[n] x2[n] = -a^nu[-n-1]
