## Boolean Algebraic operators:

**BOOLEAN ALGEBRA:** “Boolean algebra is a convenient arid systematic way of expressing and analyzing the operation of logic circuits”

## Logical operators:

There are three basic logical operators used in Boolean algebra.

## OR:

OR operation is represented by a “+” sign. It is used for logical addition or Boolean sum. For example, A and B and the resulting value of C in the equation

A+ B= C It is read as ” AOR Bis equal to C”. It may be noted that as there are two variable A and B So only 4 (22) combinations of inputs are possible.

##

## AND:

This operation is represented by dot “.”. It is used for logical multiplication. The AND operation is defined by listing all possible combinations of, for example, A and B and the resulting value of C in the equation A.B = C or AB = C read as “A AND Bis equal It 0 C”

## NOT:

This operation is represented by a prime (‘) or bar (-) on the variable. It is used for complement operation. For example, A (read as A bar) means the complement of A or NOT A.
