1. Submit MATLAB programs and their plots of the following sequences over the indicated interval.
(a)
x(n) = 28(n+2) -8(n-4), -5≤n ≤ 5.
x(n) = n[u(n)-u(n-10)] 0 ≤ n ≤ 20.
(b)
2. It is useful to plot the continuous time signal on the same plot. All signals in MATLAB are discrete-time, but they will
look like continuous-time signals if the sampling rate is much higher than the Nyquist rate. Please fill in the "Problem to
solve" region below to show the Nyquist rate. Submit the final code and its graph.
