Please use MATLAB

For all the questions below, use a time resolution of 10ms for your time axis: t -3:0.01:3. You need to submit only one script that addresses answers for all three questions below with three different figures. Remember your script should be self-sufficient and run without any errors to receive any points. Question 1 (20 points). Plot the following signals a(t) and b(t) using MATLAB. Label all the axis, signals and the figure accordingly. When you run your script, it should automatically plot the figure, as shown below. aft) should be traced in red and b(t) should be traced in blue. See the following documentation for detailed explanation of how to plot signals using MATLAB, as well as the MATLAB resources provided in the syllabus thw signals vs time 2.5 2 1.5 0.5 0 -0.5 3 time (s)
