engineering recuitment GATE IN Test Series 2023-24 Mock Test Control Systems Frequency Response Analysis Bode Plot
The open-loop transfer function of the system is:
\(G\left( s \right)H\left( s \right) = \frac{{10{{\left( {s + 5} \right)}^2}}}{{s\left( {s + 2} \right)\left( {s + 10} \right)}}\)
With respect to the Bode magnitude plot, which of the following is / are correct?1
Magnitude at ω = 0.1 rad / sec is 20 dB
2
Initial slope of the line is -20 dB / decade
3
Slope of the line between frequency 5 rad / sec to 10 rad / sec is +40 dB / dec
4
Slope of the line at high frequency is -20 dB / dec
