![]() ![]() Thus the above equations can be written as Though this problem can be solved with the help of an EXOR Gate, if you do care about the output, the sum result must be re-written as a 2-bit output. These are the least possible single-bit combinations. Let us first take a look at the addition of single bits. With the help of half adder, we can design circuits that are capable of performing simple addition with the help of logic gates. When I say, calculator, I don’t mean one with buttons, this one is a circuit that can be integrated with many other circuits for a wide range of applications. TAKE A LOOK : FLIP FLOPS What is an Adder?Īn adder is a kind of calculator that is used to add two binary numbers. Single-bit Full Adder circuit and Multi-bit addition using Full Adder is also shown.īefore going into this subject, it is very important to know about Boolean Logic and Logic Gates. Design of Full Adder using Half Adder circuit is also shown. Half Adder and Full Adder circuits is explained with their truth tables in this article.
