THE n VALUE IS : 12

n = 12

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 22008942, 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.
