Question 1.
What output does an XOR gate produce when both inputs are 0?
Show hintHide hint
Check the truth table of the XOR gate.
Question 2.
If XNOR gate inputs are (1, 1), what is the output?
Show hintHide hint
Consider the condition for XNOR being true.
3Question 3.
What does the output of the XOR gate signify when both inputs are high?
- 1
- 0
- undefined
Show hintHide hint
Recall the XOR truth table.
4Question 4.
True or False: The XNOR gate outputs high when inputs differ.
- True
- False
Show hintHide hint
Think about what XNOR actually checks.
Question 5.
Design a CMOS circuit that incorporates both XOR and XNOR gates to implement a two-bit comparator.
Show hintHide hint
Think about the relationships between the bits to determine equality and inequality.
Question 6.
Explain how you would modify a standard XOR circuit to handle more than two inputs.
Show hintHide hint
Focus on how binary addition could be extended across multiple bits.
