NAND and NOR Gates

Front

What is the basic function of a NAND gate?

Back

Performs the opposite function of an AND gate

Front

What is the basic function of a NOR gate?

Back

Performs the logical NOR operation

Front

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

Back

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

Front

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

Back

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

Front

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

Back

(A && B && C)'.

Front

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

Back

(A + B + C)'

Front

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

Back

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

Front

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

Back

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.

Front

What are the applications of NAND gates in electronic circuits?

Back

Logic gates, memory units, and arithmetic circuits

Front

What are the applications of NOR gates in electronic circuits?

Back

Logic gates, memory circuits, and digital signal processing
