MATLAB Program and Plots. For each of the following parts, turn in your MATLAB code and plots together on a single sheet of paper. Not following these directions will incur deductions. You may combine solutions such that more than one solution is provided on a single page. (a) On two separate plots show the real and imaginary components to the function x(t) = Ce^at for C = 0.5 + j0.5 and a = 0.5 + j10 on the interval t = [-3, 3] with a spacing between measurements of Delta t = 0.01. (b) Shift the signal to the left by 1 second and replot. State what you modified in x(t) to effect this change. (c) Compute the modifications to C and/or a to achieve zero phase for the signal x(t). Replot the signal real and imaginary parts to verify your solution and turn in your analytical work, program and verification plots
