Question

give the deffirence between half adder and full adder. draw the diagram of full adder. write their truth tables​

Answer 1

Answer:

Full Adder is the adder which adds three inputs and produces two outputs which consists of two EX-OR gates, two AND gates and one OR gate.

...

Difference between Half adder and full adder :

S.No. Half Adder Full Adder

3 In Half adder there are two input bits ( A, B). In full adder there are three input bits (A, B, C-in).

Answer 2

Explanation:

S.No Half Adder Full Adder 1. A combinational circuits that performs the addition of two bits is called a half adder A combinational circuit that performs the addition of three bits (two bits are significant and one is a previous carry) is called a full adder 2. The half adder circuits needs two binary inputs and two binary outputs. It consists of three binary inputs and two binary outputs. 3. Half adder does not have carry in input. Full adder has carry in inputRead more on Sarthaks.com -
