(a) Figure Q1(a) is plotted using MATLAB to differentiate between a continuous-time signal and a discrete-time signal. Write a script to plot the two figures by assigning the correct variables such as amplitude, frequency, time (or index) range, and the labels. Then, show the output of your script.
