GATE EC 2012 Question Paper (12-Feb-2012) (Shift 2)

Consider the given circuit. In this circuit, the race around

The output Y of a 2-bit comparator is logic 1 whenever the 2-bit input A is greater than the 2-bit input B. The number of combinations for which the output is logic 1, is

The i-v characteristics of the diode in the circuit given below are

$i=\{\begin{array}{ccc}\frac{v-0.7}{500}A& & v\ge 0.7V\\ 0A& & v<0.7V\end{array}$

The current in the circuit is

In the following figure, C₁ and C₂ are ideal capacitors. C₁ has been charged to 12 V before the ideal switch S is closed at t = 0. The current i(t) for all t is

The average power delivered to an impedance (4 – j3) Ω by a current 5 cos (100πt + 100) A is
