engineering recuitment UPMRC JE 2024 Mock Test Control Systems Frequency Response Analysis Bode Plot
The frequency response of a linear system G(jω) is provided in the tabular form below
| G(jω) | 1.3 | 1.2 | 1.0 | 0.8 | 0.5 | 0.3 |
| ∠G (jω) | -130° | -140° | -150° | -160° | -180° | -200° |
The gain margin and phase margin of the system are
1
6 dB and 30°
2
6 dB and -30°
3
-6 dB and 30°
4
-6 dB and -30°
