Question 2. .. . . . ...15 marks The impulse response of a system h(t) = u(t + 1) -u(t -1) is shown in figure below. Find and plot the output y(t) of the system to the input x(t) that is convolution of the signal x(t) with h(t). All the details of your work are required in order to receive marks for this question. You can use flip and shift or any mathematical approach to solve this problem. Find and simplify the complete mathematical expression for signal y(t). x ( t ) + -1 -1 h (t )
