Expert Solution
Step 1

Z transform is used to convert the discrete signal in to frequency domain.

Z transform is  discrete equivalent of Laplace transform. 

The z transform of x(n) is given by below formula

X(z)=∑n=-∞∞x(n)z-n


Range of value of z for which the summation converge is called ROC.

ROC is the region for which the Z transform exist.
