Question

Difference between full adder and half adder

Answer 1

Half Adder and Full Adder Circuit. An adder is a digital circuit that performs addition of numbers. The half adder adds two binary digits called as augend and addend and produces two outputs as sum and carry; XOR is applied to both inputs to produce sum and AND gate is applied to both inputs to produce carry.
The main difference between the Full Adder and the previous Half Adder is that a full adder has three inputs. The same two single bit data inputs A and B as before plus an additional Carry-in (C-in) input to receive the carry from a previous stage as shown below.

Answer 2

The difference between full - adder and half - adder are

Full - adder :- It accept two input bit and an input carry and generate a sum output and an output carry .

Half adder :- it accept two binary digit on input and produce two binary digit on it's output (a sum bit and a carry bit )
