Understanding Boolean Logic

What is the symbol for the AND gate?

• Two parallel lines (||)

• A circle with a line through it (⊕)

• A flat line with a D shape (∧) or a combination of two inputs leading to one output.

• A flat line with a triangle shape (→)

What is the function of a NOT gate?

• The function of a NOT gate is to combine multiple signals.

• The function of a NOT gate is to amplify the input signal.

• The function of a NOT gate is to pass the input signal unchanged.

• The function of a NOT gate is to invert the input signal.

How many inputs does an OR gate have?

• An OR gate can have exactly 3 inputs.

• An OR gate can have 2 or more inputs.

• An OR gate can only have 1 input.

• An OR gate can have a maximum of 5 inputs.

What is the output of a NAND gate when both inputs are 1?

What is the symbol for the NOR gate?

• An AND gate symbol with no circle

• The symbol for the NOR gate is a combination of an OR gate symbol with a small circle at the output.

• A triangle with a line at the output

• A simple circle with no connections

Define the function of an XOR gate.

• The function of an XOR gate is to output false if at least one input is true.

• The function of an XOR gate is to output true if both inputs are true.

• The function of an XOR gate is to output true if both inputs are false.

• The function of an XOR gate is to output true if exactly one of its inputs is true.
