An AND gate and an OR gate produce opposite output.

1

The circle in the logic symbol of a NOT gate is known as what?

1

Which gate produces a 1 only if all its inputs are 1 and a 0 otherwise?

1

A transistor is made of material that acts as a good insulator, such as rubber.

1

If an electrical signal is grounded, the electricity literally flows harmlessly to the ground.

1

Which gate does the following Boolean expression represent?
X = A • B

1

Which gate does the following truth table represent?

1

A logic diagram and a truth table are equally powerful techniques for describing the behavior of a circuit.

1

DeMorgan's law states that inverting the output of an AND gate is equivalent to inverting the individual input signals and then passing them through an OR gate.
