Question

Draw the truth table of a Half adder.Draw the logical circuitdiagram of a half Adder. Write Boolean expressions for all theoutput signals of half adder circuit.

Answer 1

Answer:

Refer to the image 1 for the truth table of Half adder.For the logic circuit also refers to the image 2.

Boolean expressions:-

Sum=A'B+AB' or A XOR B

Carry=A.B

Explanation:

In the output expression we have two outputs one is the sum and the other one is carry.Sum is 1 when either of the input is 1 and the carry is 1 when the both inputs are 1.
