The Bode magnitude plot of the open loop transfer function G(s) of a certain system is shown below:
If the system is of minimum phase type, then the open-loop transfer function G(s) will be given by:
1
\( {10^6(s+20)^2(s+5)^2 \over (s+40)^2(s+100)}\)
2
\( {10^5(s+40)^2 \over (s+5)^2(s+20)^2(s+100)}\)
3
\( {10^6(s+20)^2 \over (s+5)^2(s+40)^2(s+100)}\)
4
\( {10^5(s+20)^2(s+5)^2 \over (s+40)^2(s+100)}\)
