Consider the following asymptotic Bode magnitude plot ( \(\omega\) is in rad/s).Which one of the following transfer functions is best represented by the above Bode magnitude plot?

• A. \(\frac{{2s}}{{\left( {1 + 0.5s} \right){{\left( {1 + 0.25s} \right)}^2}}}\)
• B. \(\frac{{4\left( {1 + 0.5s} \right)}}{{s\left( {1 + 0.25s} \right)}}\)
• C. \(\frac{{2s}}{{\left( {1 + 2s} \right)\left( {1 + 4s} \right)}}\)
• D. \(\frac{{4s}}{{\left( {1 + 2s} \right){{\left( {1 + 4s} \right)}^2}}}\)
