Gates and Functions Quiz

What is the basic operation of an AND gate?

• Gives low output if any of the inputs are high

• Gives high output only if all inputs are high

• Produces an inverted version of the input at its output

• Gives high output if one or more inputs are high

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

• NOR gate

• EXOR gate

• NAND gate

• EXNOR gate

What is the symbol used to represent the Exclusive-OR gate?

• Dot (.)

• Plus (+)

• Encircled plus sign ()

• Small circle on the output

What is the purpose of a NOT gate?

• Produces an inverted version of the input at its output

• Gives high output only if all inputs are high

• Gives low output if any of the inputs are high

• Gives high output if one or more inputs are high

Which gate can be used to make a NOT gate?

• AND gate

• OR gate

• NOR gate

• NAND gate

What is the function of a NOR gate?

• Produces an inverted version of the input at its output

• Gives low output if any of the inputs are high

• Gives high output only if all inputs are high

• Gives high output if one or more inputs are high

What is the output of an EXNOR gate if both inputs are high?

• No output

• Inverted output

• Low

• High

Which gates are called universal functions?

• AND and OR gates

• NOT gates

• NAND and NOR gates

• EXOR and EXNOR gates

What is the purpose of a truth table?

• To provide power supply to gates

• To represent the symbol of a gate

• To show the function of a logic gate

• To generate multiple input gates

How are multiple input gates made?

• By joining gates of the same type with less inputs

• By using different types of gates

• By using only NOR gates

• By using only NAND gates
