B-2-3. Simplify the block diagram shown in Figure 2-31 and obtain the closed-loop transfer function C(s)/R(s). Figure 2-31 Block diagram of a system. R(s) G₁ H₁ G₂ H₂ H3 |x G3 C(s)

Help with deriving formula.

The output response is as in figure-b, while applying the unitstep function to the system input given in the figure-family block diagram belowis happening. T and are the constant numbers seen in the open loop transfer function. Calculate the constant.
