I am doing participate in the exam of Electronic Corporation of India Limited placement paper and I want to know about its papers pattern so please tell me about this papers pattern

[Saksham]

I have given exam pattern of Electronic Corporation of India Limited.

The paper consists of only 50 technical questions, 2 hours.

The placement paper consists following type of question.

1. Consider the following expressions indicating the step or impulse response of an initially relaxed control system-

1. (5 – 4e-2+) u(t)
2. (e-2t +5) (u(t))
3 .V(t) + 8e-2t u(t)
4 . V(t) + 4e-2t 4(t)

2. Those which correspond to the step and impulse response of the same system include- 1&3
Which is the following relate to rational transfer function of a system-
