5. Determine the CT convolutions for the signals below. Sketch the signal that flips and on same plot the
one that is not flipped. Do this for each overlap case. Clearly indicate all overlap cases and the integral
limits. Finally, using the left squiggly bracket notation, show the output for each case versus time.
