2 cards from this section. Quick, good the night before a test.
What are the outputs of a Half Adder when the inputs are both 0?
Think about what 'adding nothing' gives you.
If A is 1 and B is 0, what is the Sum and Carry?
Keep in mind that the Sum is calculated using XOR logic.
What is the output Sum when both inputs of a Half Adder are 1?
Recall how binary additions work.
The Half Adder produces a Carry output only when:
Think about binary addition.
Design a Half Adder circuit using only NAND gates. Explain the logic behind the construction.
Explore how to manipulate NAND gates to create other logic gates.
Analyze how increasing the number of Half Adders in a multi-bit adder can introduce delays and describe a solution to manage this.
Think about how multi-bit processing requires speedy operations.
