Half adder

circuit is half adder

this gate is half adder

This is an half adder circuit, it takes two one bit binary digits and adds them to produce a sum bit and a carry bit, however this circuit is incapable of adding more than one bit binary digit hence it is known as the binary half adder

A circuit that adds two 3-bit numbers using a half-adder and a full-adder.

A circuit that takes two decimal numbers A and B as input and then splits in into their corresponding three bits using a splitter and then calculates their summation using XOR, AND and OR gates. This generates 4 output lines for 4 bits of the summation, and a reversed splitter is finally used to join the output lines to produce a 4-bit output and displayed using a Hex-Display.

This is a ripple-carry adder.

half adder with 0,0 input

Half adder is a combinational logic circuit with two inputs and two outputs. The half adder circuit is designed to add two single bit binary number A and B. It is the basic building block for the addition of two single-bit numbers. This circuit has two outputs carry and sum.
