2. | In a minimum phase system |
|||||||
Answer: Option B Explanation: For stability poles must be in left half plane. Zeros in left half plane lead to minimum phase shift. |
4. | The given figure shows a pole zero diagram. The transfer function G(j1) is |
|||||||
Answer: Option A Explanation: Join j1 point with the zero and poles. Find magnitude and phase angles of all these lines. |
5. | The system in the given figure, has |
|||||||
Answer: Option D Explanation: Since the plot is very near (-1 + j0) point, gain margin is poor. |
7. | In the given figure, if R = XC, voltage gain is |
|||||||
Answer: Option C Explanation: If R = XC, V0 = 0.5 Vi Hence gain is -3 dB. |
