In the following circuit, the output Y for all possible inputs A and B is expressed by the truth table

Which of the following gates corresponds to the truth table given below?

The following circuit is equivalent to 

If a signal passing through a gate is inhibited by sending a LOW into one of the inputs, and the output is HIGH, the gate is a(n):

If the output $$Y$$ of the following circuit is $$1$$, the inputs $$ABC$$ must be :

The following arrangement performs the logic function of _________ gate.

A logic gate which has an output $$'1'$$ only when the inputs are complement to each other is.

A photoelectric cell emits electrons when illuminated by a $$60\ W$$ bulb. If the same cell is illuminated by replacing it with a $$40\ W$$ bulb, the observation that can be made is

If we add impurity to a metal those atoms also deflect electrons. Therefore,

To get an output $$y = 0$$ from the circuit shown in the figure, the input $$C$$ must be
