NAND and NOR Gates

What is the basic function of a NAND gate?

• Only works with binary inputs

• Performs the opposite function of an AND gate

• Can only be used in digital circuits

• Performs the same function as an OR gate

What is the basic function of a NOR gate?

• Executes the logical XOR operation

• Performs the logical AND operation

• Performs the logical NOR operation

• Acts as a memory unit

Draw the truth table for a 2-input NAND gate.

• The truth table for a 2-input NAND gate is: 00 -> 0, 01 -> 0, 10 -> 0, 11 -> 1

• The truth table for a 2-input NAND gate is: 00 -> 0, 01 -> 1, 10 -> 1, 11 -> 0

• The truth table for a 2-input NAND gate is: 00 -> 1, 01 -> 1, 10 -> 1, 11 -> 0

• The truth table for a 2-input NAND gate is: 00 -> 1, 01 -> 0, 10 -> 0, 11 -> 1

Draw the truth table for a 2-input NOR gate.

• The truth table for a 2-input NOR gate is: Input A | Input B | Output 0 | 0 | 1 0 | 1 | 0 1 | 0 | 0 1 | 1 | 0

• Input A | Input B | Output 0 | 0 | 0

• Input A | Input B | Output 1 | 0 | 1

• Input A | Input B | Output 1 | 1 | 1

What is the Boolean expression for a 3-input NAND gate?

• (A || B || C)'

• (A && B && C)'

• (A && B || C)'

• (A && B && C)

What is the Boolean expression for a 3-input NOR gate?

• (A + B + C)

• (A + B * C)

• (A * B * C)

• (A + B + C)'

Explain the concept of 'universal gates' in the context of NAND and NOR gates.

• NAND and NOR gates are not considered universal gates

• NAND and NOR gates are considered universal gates because any other logic gate can be constructed using only NAND gates or only NOR gates.

• NAND and NOR gates are only used in specific types of electronic circuits

• Universal gates are only used in computer programming

Compare and contrast the operation of a NAND gate and a NOR gate.

• Both gates are universal gates, but their outputs are opposite. NAND gate gives high output only when both inputs are low, while NOR gate gives low output only when both inputs are high.

• NAND gate gives high output only when both inputs are high, while NOR gate gives low output only when both inputs are low.

• NAND gate gives low output only when both inputs are low, while NOR gate gives high output only when both inputs are high.

• NAND gate and NOR gate have the same output for all input combinations.

What are the applications of NAND gates in electronic circuits?
