Introduction to Logic Gates and Logic Circuits

What does a NOT gate do?

• It outputs the same as the input.

• It reverses the input.

• It outputs true if at least one input is true.

• It outputs true if both inputs are true.

What is the output of an AND gate if both inputs are true?

• True

• One

• Zero

• False

Which gate outputs true if at least one of its inputs is true?

• NOT gate

• OR gate

• NAND gate

• AND gate

What is the output of a NAND gate if both inputs are true?

• True

• One

• False

• Zero

Which gate is a combination of an OR gate and a NOT gate?

• AND gate

• NAND gate

• NOR gate

What is the output of an XOR gate if both inputs are true?

• One

• Zero

• False

• True

Which gate has a symbol that looks like the letter 'D'?

• NAND gate

What is the output of a NOR gate if both inputs are false?

• True

Which gate has only one input?

• NOT gate

• OR gate
