A full adder is used for all other digits in addition, how many logic gates will it use?
A
3
B
4
C
5
D
2
Explanation: 

Detailed explanation-1: -A Full Adder consists of one OR gate and two EX-OR and AND gates. There are two inputs in a Half Adder-A and B. There are a total of three inputs in a Full Adder-A. B. C-in.

Detailed explanation-2: -Full adder includes two EX-OR gates, two OR gates, and two AND gates. The input bits in the half adder are two like A, B.

Detailed explanation-3: -A full adder circuit is central to most digital circuits that perform addition or subtraction. It is so called because it adds together two binary digits, plus a carry-in digit to produce a sum and carry-out digit. It therefore has three inputs and two outputs.

Detailed explanation-4: -Design of a 5-bit Adder – Description The 3-bit offset ranges from decimal 0 to 7, while the relative address ranges from decimal 0 to 24 – in other words, it will never take on values corresponding to decimal 25-31.

Detailed explanation-5: -So, in the given question to add 4-bit binary numbers requires 1 half adder and 3 full adders.
