Logic circuit of Half Adder using only basic gates: Then the Boolean expression for a half adder is as follows.Ĭircuit of the half adder using Boolean function of SUM and CARRY. Let’s see the truth table for four different input sets-įrom the truth table of the half adder we can see that the SUM ( S) output is the result of the Exclusive-OR gate and the Carry(C) is the result of the AND gate. So four different input sets or combination can be generated using two bits. The half adder produces a sum and a carry value which are both binary digits. There are two types of Adder:Ī half adder is a logical circuit that performs an addition operation on two binary digits.
It is mainly designed for the addition of binary number, but they can be used in various other applications like binary code decimal, address decoding, table index calculation, etc. You will be able to implement Full adder circuit using Half adder circuit.ĥ. You will be able to explain binary adder circuit.Īn adder is a combinational circuit or digital circuit in electronics that implements or performs addition of numbers. You will be able to describe Full Adder circuit.Ĥ. You will be able to describe Half Adder circuit.ģ. You will be able to explain Adder circuit.Ģ.
