Match List-I with List-II and select the correct answer using the codes given below the lists:
-
- A B C D
1 3 2 4 - A B C D
3 1 2 4 - A B C D
2 1 4 3 - A B C D
4 2 1 3
- A B C D
Correct Option: B
From the given transfer function
| A. T.F. = | = | + | |||
| (s + α)(s + β) | (s + α) | (s + β) |
= Ae– αt + Be– βt
Which is exponential decay, similarly for
| B. T.F. = | = | + | |||
| (s - α)(s - β) | (s - α) | (s - β) |
= Aeαt + Beβt
Which is exponential grow. Similary for the T.F. given in C and D one is stable and other is unstable system. Hence we get
(a) – 3
(b) – 1
(c) – 2
(d) – 4
