Answer ALL the questions Question 1 126 marks1 (a) The transfer function of a continuous time system, SYSTEM A, is given as below: where X(s) and Y(s) are the Laplace transforms of the input x(t) and the output y(t) of the SYSTEM A, respectively. By the use of Laplace Transform, determine the output y(i) if x(t) = sin(2i)u(t). 114 marks] (b) Determine the peak-to-peak amplitude of the output y(t) at the steady state. [6 marks] (c) Draw the direct realization of the SYSTEM A if only integrators, gains and adders are to be used. You must keep the number of integrators to a minimum. 16 marks]
