It is shown in Figure 5.6(c) that when negative feedback is used, the overall transfer function for the system of Figure 5.6(b) is

Develop the block diagram of an alternative feedback system that will result in the same closed-loop transfer function, C(s) = R(s), with G(s) unchanged and unmoved. In addition, your new block diagram must have unity gain in the feedback path. You can add input transducers and/or controllers in the main forward path as required.

C(s). G(s) R(s) 1+ G(s)H(s)
