Reduce the given circuit in figure $($A$)$ below to a single block to obtain the forward part $($closed loop$)$ transfer function, $G(s)$ as in Figure B$.$ You need to write what action you are taking at each step and draw intermediate diagrams. The final answer is not sufficient; you need to show the work. Also, $G(s)$ must be a ratio of polynomials in s$,$ such as N$($s$)/$D$($s$).$ Also, you can use Simulink to verify the answer by modelling it as given in figure A$,$ and final transfer function $G(s)$ on step and ramp inputs.
