ELE 307 / CPE 321 ASSIGNMENT I Each student will need to solve the following questions, by using MATLAB or octave-online. N.B: the n stands for the multiplication of each student's last number. For example, if the student number is 21901009, n = 2 * 4 = 8. Furthermore, if the student has n = 0 after the multiplication of the last two digits, take n = 4. Each student will upload the result on the Moodleno need for a hard copy. Question 1 Figure 1 illustrates a discrete-time signal. Create a diagram for each of the following signals. (a) x[n - 2] (b)x1-n + 4] (c) x[3n] Question 2 Use Octave or MATLAB to plot the signal x(t) = ne-0.tsin(4nt) + ne-tsin(2nt) X[N] 1 -2 -1 0 1 5 6 2 N-AXIS Figure 1: A discrete-time signal
