Question 1.
What does a NAND gate output when both inputs are LOW?
Show hintHide hint
Think about how NAND behaves when inputs are false.
Question 2.
What is the primary function of a NOR gate?
Show hintHide hint
Recall how NOT affects an OR operation.
3Question 3.
What is the main characteristic of universal gates?
- They can perform only basic operations
- They can construct any logic gate
- They are slower than other gates
Show hintHide hint
Think about their versatility.
4Question 4.
True or False: The output of a NAND gate is HIGH only when both inputs are HIGH.
- True
- False
Show hintHide hint
Recall the definition of NAND.
Question 5.
Given the behavior of NAND and NOR gates, design an expression that uses them to replicate a basic OR function using only NAND gates.
Show hintHide hint
Consider how NAND can be used to invert the result.
Question 6.
How can you create a NOT gate using only a NOR gate?
Show hintHide hint
Think about how NOR behaves with equal inputs.
