12. In an LTI system, x(n) is the input and h(n) is the
unit-sample response. Find and sketch the
output y(n) for the following cases:
i) x(n) = 2[u(n) - u(n - 11)] and h(n) = 0.5nu(n)
ii) x(n) = 2[u(n) - u(n - 11)] and h(n) = (-0.5)nu(n)
iii) x(n) = u(n) - u(n - 5) and h(n) = 0.5|n|u(n)
iv) x(n) = u(n) - u(n - 5) and h(n) = (-0.5)|n|u(n)
