There is a LTI system whose system function is shown below. You are required to realize the Transfer Function using the Direct Form II realization method. H(z) = (1-z-¹)(1+2z-¹) a. Make the Transfer Function a product of two Transfer Functions where H(z) H1(2). H2(z) 10 marks b. Determine the two difference equations w(n) and y(n) from the two transfer functions established in (a) above I 6 marks c. Sketch the Direct Form II Realization diagram for the two transfer functions.
