. For a system with block diagram shown in Figure 3 where \[ \begin{array}{l} G(s)=\frac{10(s+20)}{s(s+2)} \\ H(s)=5 s+1 \end{array} \] - Obtain the expression of close-loop transfer function and identify the gain constant of the system; - Manually sketch the asymptotic straightline approximation for Bode magnitude diagram of its open-loop transfer function on a semi-log graph paper (provided below) \( { }^{* *} \) please show the calculation of all corner frequencies and starting point.
