Logic circuits are being designed by the use of Boolean Algebra. Schematic Form of NOT Rule. Identity: 0 + x = x ; 1 x = x 3. This form of algebra is used to simplify and help decision-making. Theorem-1: X + X = X Proof: Select X as 0 then 0+0 = 0, select X = 1 then 1 + 1 = 1 results: X+ X = X. It was named after George Boole who discovered a link between Mathematics and logic in the year 1854. Those are the only two values we'll deal with in Boolean algebra or digital electronics for that matter. Because of this, Boolean algebra is suited to variables that have two states, such as YES or NO answers, or the binary number system where answers are either 0 or 1. Boolean Algebra is an algebra, which deals with binary numbers & binary variables. Conference Paper. It is used to analyze digital gates and circuits It is logical to perform a mathematical operation on binary numbers i.e., on '0' and '1'. a) Addition and subtraction.

Boolean Algebra uses a set of Laws and Rules to define the operation of a digital logic circuit A set of rules or Laws of Boolean Algebra expressions have been invented to help reduce the number of logic gates needed to perform a particular logic operation resulting in a list of functions or theorems known commonly as the Laws of Boolean Algebra. De Morgan's Theorem : DE Morgan's Theorem represents two of the most important rules of boolean algebra. 16 maxterms The first chapter presents the algebra of sets from an intuitive point of view, followed by a formal presentation in chapter two of Boolean algebra as an abstract algebraic system, with no reference to applications. Boolean Function: consists of binary variable, constants 0 & 1, logic operation symbols, parenthesis and equal to operator. It can have a 0 or 1 value. B)' = A' + B'. Boolean algebra is the combination of logic and algebra, initially developed by George Boole, for whom the subject is named, in the 1840s and '50s, and later refined by other logicians. Boolean algebra is the branch of algebra in which the values of the variables are True and False, usually denoted 1 and 0 respectively. The Boolean variables are represented as binary numbers to represent truths: 1 = true and 0 = false. Boolean logic is a subsection of algebra that describes a set of simple rules and gates to help compare and manipulate logical statements.
