Question 2 (a) Consider the LTI system illustrated in Figure Q2(a) with three interconnected LTI subsystems whose impulse responses are hi(t), hz(t), and hz(t). Describe the impulse response of the whole system h(t) in terms of hi(t), hz(t) and hz(t). (3 marks) hi(t) x(t) y(t) h(t) hz(t) h(t) Figure 02(a) Given hi(t) = e-t for t20 , hz(t) = et fort<0 and hz(t) = u(t). Determine the LTI system response h(t) defined in Question Q2(a) using graphical convolution method. (15 marks) A system is defined by the difference equation y[n] – 4y[n – 1] + 4y[n – 2] = x[n – 1]. Solve the above difference equation and obtain the homogenous solution. (7 marks) (c)
