A bulb in a staircase has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by any one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles (A) an AND gate (B) an OR gate (C) an XOR gate (D) a NAND gate Q.3 Two systems with impulse responses 1( ) h t and 2 ( ) h t are connected in cascade. Then the overall impulse response of the cascaded system is given by (A) product of 1( ) h t and 2 ( ) h t (B) sum of 1( ) h t and 2 ( ) h t (C) convolution of 1( ) h t and 2 ( ) h t (D) subtraction of 2 ( ) h t from 1( ) h t \Q.4 In a forward biased pn junction diode, the sequence of events that best describes the mechanism of current flow is (A) injection, and subsequent diffusion and recombination of minority carriers (B) injection, and subsequent drift and generation of minority carriers (C) extraction, and subsequent diffusion and generation of minority carriers (D) extraction, and subsequent drift and recombination of minority carriers Q.5 In IC technology, dry oxidation (using dry oxygen) as compared to wet oxidation (using steam or water vapor) produces (A) superior quality oxide with a higher growth rate (B) inferior quality oxide with a higher growth rate (C) inferior quality oxide with a lower growth rate (D) superior quality oxide with a lower growth rate Q.6 The maximum value of q until which the approximation sin q q » holds to within 10% error is (A) 10° (B) 18° (C) 50° (D) 90° GATE EC Branch Sample Paper     pdf file atteched................... |
