Consider the transfer function G(s) = 10/s, the frequency at which the magnitude of G(S) = 0 dB in bode plot is
- A. For all frequencies < 1 rad/s
- B. For all frequencies < 10 rad/s
- C. 1 rad/s
- D. 10 rad/s
Answer: D. 10 rad/s
Explanation: Magnitude |G(jω)| = 10/ω. In dB, 20 log10(10/ω) = 0 dB when ω = 10 rad/s (the gain crossover frequency).
