5. Consider a continuous-time, linear time-invariant system with unit impulse response function given by h(t) = 8(t+2)+(t-2) (a) Find the frequency response of the system. Simplify as much as you can. 15 points) (b) Sketch the magnitude and phase response of the system. Label the axes and show enough details to demonstrate your understanding of the material. [6 points (c) Find the output of the system when the input is r(t) = cos(at) by convolving h(t) with r(t). [7 points) (d) Find the output of the system when the input is r(t) = cos(Tt) using the fre- quency response you derived. Simplify as much as you can. [7 points)
