2. Look at the example on slide #8 (which was explained in the video). Find the z-transform of the right-sided signal x[n] = 2 (3)$^n$u[n] Use the following z-transform pair: x[n] = a$^n$u[n] $\leftrightarrow$ X(z) = $\frac{z}{z - a}$ ROC: $|z| > |a|$ Plot any poles and zeros. Shade in the ROC.

Determine the z-transform of each of the following signals using the Z-transform and find its ROC. a. x[n] = u[n+2] - u[n-5] b. x[n] = (1/2)^{n-1}u[n-2] c. x[n] = (1/3)^{n+2} cos(pi*n/2 + pi/2) u[n] d. x[n] = 2^n u[1-n] e. x[n] = (1/2)^n {u[n] - u[n-10]}

In an application, time domain signals need to be represented as frequency domain. For that, a transform is used. Consider the following signals: x1[n] = (1/2)^n u(n) x2[n] = -(1/2)^n u[-n - 1] i. Find the regions of convergence of the Z-transforms of x1[n] & x2[n]. ii. Determine the Z-transform of x1[n] + x2[n] and indicate the ROC. iii. Find the Z transform for x(n) = 3e^-2n u(n) + 2[4^n u(-n - 1)] + 5δ(n)
