Logic 0 is a low voltage signal (around 0 volts) Logic 1 is a high voltage signal (e.g. 5 or 3.3 volts) Having only two logic values (0 and 1) simplifies the implementation of the digital circuit Postulates of Boolean Algebra 1. Closure: the result of any Boolean operation is in B = {0, 1} 2. Identity element with respect to + is 0: T+0=0+ T= T

Boolean algebra and Logic Gates BOOLEAN OPERATIONS AND EXPRESSIONS Variable, complement, and literal are terms used in Boolean algebra. A variable is a symbol used to represent a logical quantity. Any single variable can have a 1 or a 0 value. The complement is the inverse of a variable and is indicated by a bar over variable (overbar).

In Boolean algebra, all the algebraic functions performed is logical. These actually represent logical operations. The AND, OR and NOT are the basic operations ...

1 Boolean Algebra and Logic Gates Boolean Algebra Two-valued Boolean algebra is also called switching algebra A set of two values: B = {0, 1} Three basic operations: AND, OR, and NOT The AND operator is denoted by a dot (·) T· U or T U is read: T AND U The OR operator is denoted by a plus (+) T+ U is read: T OR U The NOT operator is denoted by (') or an overbar (¯).

An OR gate is a logic circuit that performs an OR operation on the circuit's input. The expression x=A+B is read as “x equals A OR B”. Page 5 ...

Section 3: Basic Rules of Boolean Algebra 5 3. Basic Rules of Boolean Algebra The basic rules for simplifying and combining logic gates are called Boolean algebra in honour of George Boole (1815–1864) who was a self-educated English mathematician who developed many of the key ideas. The following set of exercises will allow you to rediscover the
