Transfer function for the following bode plot shown in the figure is [Figure description: A Bode magnitude plot (M in dB versus log ω). The magnitude line starts at 20 dB at ω = 0.1 and falls with a constant slope of -40 dB/decade, crossing 0 dB further right.]
- A. 0.1 s^2
- B. 0.1/s^2
- C. 10/s^2
- D. 20/s^2
Answer: B. 0.1/s^2
Explanation: Initial slope of -40 dB/decade indicates a double pole at the origin (1/s²), with gain factor K = 0.1, giving 0.1/s².
