Question 1 The stem plot of a signal, x[n], is shown below: 0 1 2 3 Express the signal x[n] as the sum of scaled, delayed unit impulse functions. [5 marks] Question 2 A Discrete Time Linear Time - Invariant (DT LTI) system, h[n], is given by: h[n] = {1, 3, 3,-1) State, giving reasons, whether the system, h[n], is: (i) (ii) Causal, anti-causal or non-causal Stable or unstable [5 marks) [5 marks) Question 3 Using the signal, x[n] from question 1 as the input to the system, and h[n] from question 2, determine the output, y[n], of the system. Express your answer in the form of a stem plot. [10+ 5 marks]
