Plotting Signals: 1. Sketch the following signals: a) xt if t ti f t f t () = <- +- < - 04 24 3 2 3 b) y(t) = x(t-1) where x(t) is defined in part a) c) xn if n ni f n f n [] = < -≤ < 02 2 4 44 d) y[n] = x[n+1] where x[n] is defined in part c) 2. Write MATLAB code to plot the signals in Problem 1. Scale your time axis so that a sufficient amount of the signal is being plotted. Use subplot to give 4 plots per page; label your plots with ’Time (sec)’ on the x-axis for the continuous time signals and ’n’ for discrete time signals.
