  1. The transfer function for the given Bode plot is–


    1. K(s + 1)
      s2{s/5( + 1)}

    2. K(s + 1)
      s{s/5( + 1)}

    3. K
      s2(s + 1){s/5( + 1)}

    4. K{s/5( + 1)}
      s2(s + 1)
Correct Option: A

From figure we conclude that two pole at origin, one pole at ω = 5 and one zero at ω = 1 so the transfer function would be of the type

T.F =
K(s + 1)
s2((s/5) + 1)

Hence alternative (A) is the correct choice.
