Match List-I with List-II and select the correct answer using the codes given below the lists:
-
- a b c d
4 3 1 5
- a b c d
3 1 2 5
- a b c d
4 1 2 5
- a b c d
1 2 3 4
- a b c d
Correct Option: A
In order to solve such type of problems, it will be better to calculate the phase at ω = 0 and ω = ∞ with the help of given transfer function.
| 1.T.F = | |
| (1 + sT1)(1 + sT2) |
φ = – tan–1 ωT1 – tan–1 ωT2
φ = 0 at ω = 0
φ = – 90° – 90° = – 180° at ω = ∞
matching with option (C)
i.e., C – 1 which is given in alternative (A) only.
Hence there is no need to solve further.
Hence alternative (A) is the correct answer.
