Basic Logic Gates and Functions

What is the function of an AND gate?

• Gives a high output if one or more inputs are high

• Produces an inverted version of the input at its output

• Gives a high output only if all inputs are high

• Gives a low output if either, but not both, of its two inputs are high

Which gate is equal to an OR gate followed by a NOT gate?

• NAND gate

• AND gate

• EXOR gate

• NOR gate

What is the symbol used to show the EOR operation?

• A dot (.)

• A plus (+)

• A small circle on the output

• An encircled plus sign ()

What is the function of a NOT gate?

• Gives a high output only if all inputs are high

• Gives a low output if either, but not both, of its two inputs are high

• Produces an inverted version of the input at its output

• Gives a high output if one or more inputs are high

Which gate is a NOT-AND gate equal to an AND gate followed by a NOT gate?

• AND gate

• NOR gate

• NAND gate

• EXOR gate

What is the symbol used to show the NOT gate?

• A small circle on the output

• An encircled plus sign

• A plus (+)

• A dot (.)

What is the function of an OR gate?

• Gives a high output if one or more inputs are high

• Produces an inverted version of the input at its output

• Gives a high output only if all inputs are high

• Gives a low output if either, but not both, of its two inputs are high

Which gate is a NOT-OR gate equal to an OR gate followed by a NOT gate?

• NOR gate

• EXOR gate

• NAND gate

• AND gate

What is the symbol used to show the Exclusive-NOR gate?

• A plus (+)

• A dot (.)

• An encircled plus sign ()

• An encircled plus sign and a small circle on the output

What is the function of a ENOR gate?

• Gives a high output if one or more inputs are high

• Produces an inverted version of the input at its output

• Gives a high output only if all inputs are high

• Gives a low output if either, but not both, of its two inputs are high
