Write MATLAB code to plot the signals in Problem 1. Scale your time axis so that a sufficient amountof the signal is being plotted. Use subplot to give 4 plots per page; label your plots with 'Time (sec)’ onthe x-axis for the continuous time signals and 'n' for discrete time signals. The y-axis should be labeled'x(t)' or 'x[n]°; the title should be the problem number. Use MATLAB to plot the following signals. Use the same instructions on plotting as given in a) x(t) = 4 cos(5rt-n/4) b) x[n]=4 cos(Tn) (Use the command stem to plot discrete-time signals.) c) x[n] = 2sin(3n) d) x(t) = cos(4t)+ 2sin(8t) e) x(t) = 3cos(4t) + sin(tt)
