Prerequisite: Half Adder in Digital Logic
Given two inputs of Half Adder A, B. The task is to implement the Half Adder circuit and Print output i.e sum and carry of two inputs.
Half Adder: A half adder is a type of adder, an electronic circuit that performs the addition of numbers. The half adder is able to add two single binary digits and provide the output plus a carrying value. It has two inputs, called A and B, and two outputs S (sum) and C (carry).
Sum = A XOR B Carry = A AND B
Input : 0 1
Output: Sum=1, Carry=0
Explaination: According to logical expression Sum=A XOR B i.e 0 XOR 1 =1 , Carry=A AND B i.e 0 AND 1 =0
Input : 1 1
Output: Sum=0, Carry=1
Explaination: According to logical expression Sum=A XOR B i.e 1 XOR 1 =0 , Carry=A AND B i.e 1 AND 1 =1
- We take two inputs A and B.
- XOR operation on A and B gives the value of the sum.
- AND operation on A and B gives the value of Carry.
Below is the implementation.
Sum 1 Carry 0
