Consider the block diagram as shown in Figure 5 below. A(s) is given as A(s)= a s+y ,where a andy are the values from your unique numbers above. Y(s)for the

block diagram of Figure 5. Use a block-diagram reductionR(s)(a) Simplify and determinemethod. (b)Consider the above bock-diagram of Figure 5. You are now required to derive the transfer function,Y (s)by using the signal flow graph method. Label in your working, the paths and loops associatedR(s)with the block-diagram. Show all your working.
