Question
How many inputs and outputs does a full adder have?
a. two inputs; three outputs
b. three inputs; two outputs
c. two inputs; two outputs
d. two inputs; one output
Solution
To determine how many inputs and outputs a full adder has, let’s analyze the characteristics of a full adder:
Inputs:
- A full adder requires three inputs:
- Two significant bits (let's call them A and B)
- One carry-in bit (C_in)
Outputs:
- A full adder produces two outputs:
- The sum bit (S)
- The carry-out bit (C_out)
Conclusion:
Based on this analysis, a full adder has three inputs and two outputs.
Final Answer:
b. three inputs; two outputs.
