GATE EE 2010 Question Paper (14-Feb-2010) (Shift 1)

Given f(t) and g(t) as shown below





The Laplace transform of g(t) is

The following karnaugh map represents a function of F



The minimized form of the function F is

The following karnaugh map represents a function of F



Which of the following circuit is a realization of above function

In the LC circuit shown in the figure initial current through the inductor is zero, initial voltage across the capacitor is 100 V. Switch S is closed at t = 0 sec. The current through the circuit is

The LC circuit shown in the figure has an inductance L = 1mH and capacitance C = 10 μF. The LC circuit is used to commutate a thyristor, which is initially carrying a current of 5A as shown in the figure below. The values and initial of L and C are same as in previous question. The switch is closed ae t = 0.If the forward drop is negligible, the time taken for the device to turn off is
