What is the name of the logic circuit which can add two binary digits?
Half adder is the name of the logic circuit which can add two binary digits.
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.
An adder is a digital logic circuit in electronics that implements addition of numbers. In many computers and other types of processors, adders are used to calculate addresses, similar operations and table indices in the ALU and also in other parts of the processors. These can be built for many numerical representations like excess-3 or binary coded decimal. Adders are classified into two types: half adder and full adder. The half adder circuit has two inputs: A and B, which add two input digits and generate a carry and sum. The full adder circuit has three inputs: A and C, which add the three input numbers and generate a carry and sum. This article gives brief information about half adder and full adder in tabular forms and circuit diagrams.
