As you want to get technical assistant (Electronics) LPSC ISRO Question Paper, so this exam selection is based on GATE score so here I am giving you electrical and communication question paper: Which of the following propositions is a tautology ? (a) (P V q) → P (b) P V (q → P) (c) P V (P →q) (Ans) (d) P → (P →q) If A be a finite set of size n, then number of elements in the power set of A x A is (a) 22n (b) 2n2 (Ans) (c) (2n)2 (d) None of these The number of different spanning trees in complete graph Kn, by Cayley's theorem is (a) 2n-2 (b) nn-2 (Ans) (c) nn-1 (d) None of these If nPr = 3024, then what will be the value of r ? (a) 3 (b) 4 (c) 6 (Ans) (d) 9 If R(t) is the auto correlation function of a real, wide-sense stationary random process, then which of the following is not correct? (a) R(t) = R(-t) (b) |R(t)| ≤ R(0) (c) R(t) = - R(-t) (Ans) (d) The mean square value of the process is R(0) The gain margin for the system with open loop transfer function G(s) H(s) = 2 (1 + s) , is s2 (a) ¥ (b) 0 (c) 1 (d) -¥ s (Ans) For full question paper here is the attachment: GATE -Electrical And Communication Engineering Question Paper |
