Consider two digital sequences: \begin{equation*} x(n) = \begin{cases} a^n, & \text{if } N \le n \le 2N\\ 0, & \text{otherwise} \end{cases} \end{equation*} and $y(n) = b^n u(n)$ Here, N is a positive integer, and a and b are two values in the interval (0, 1). a) Using the time-domain approach, determine the convolution $w = x * y$ as a function $w(n)$ of only index n. b) Using the z-domain approach, determine the convolution $w = x * y$ as a function $w(n)$ of only index n. c) Using the time-domain approach, determine the cross-correlation sequence $r_{xy}(l)$ as a function of only l. d) Using the z-domain approach, determine the cross-correlation sequence $r_{xy}(l)$ as a function of only l.
