Question 1.
What are the two outputs of a Half Adder?
Show hintHide hint
Think about what happens when you add two binary numbers.
Question 2.
What is the value of Sum when A = 1 and B = 0?
Show hintHide hint
Consider which logical operation corresponds to addition.
3Question 3.
The output 'Sum' in a Half Adder is obtained through which operation?
- AND
- OR
- XOR
Show hintHide hint
Remember how XOR behaves with similar and different inputs.
4Question 4.
If both inputs A and B are 1, what is the Carry output of a Half Adder?
- True
- False
Show hintHide hint
Consider what a Carry represents in addition.
Question 5.
Design a circuit using transistors that can simulate a Half Adder. Describe the logic and reasoning behind your design.
Show hintHide hint
Think about how transistors work like switches.
Question 6.
If you have multiple Half Adders cascaded to create a 4-bit adder, explain how they would handle carry bits between each pair.
Show hintHide hint
Consider how binary addition carries over sum results.
