pbte.edu.pk11.3 Fundamental Concepts of Boolean Algebra: Boolean algebra is a logical algebra in which symbols are used to represent logic levels. Any symbol can be used, however, letters of the alphabet are generally used. Since the logic levels are generally associated with the symbols 1 and 0, whatever letters are used as variables that can

Logic Gates and truth tables
tdck.weebly.com2. Rules of Boolean algebra A ^ ¬A = 0 (Because when A =1 Output = 0, A = 0 output = 0) A V ¬A = 1 (Because one of the terms will always be a 1) When a Boolean expression is not in the simplest form it can make it difficult to understand and the logical statement may require many logic gate components so it is not an efficient circuit.

DeMorgan’s Theorem DeMorgan proposed two theorems that are used frequently in Boolean algebra. The first theorem states: The complement of two variables ANDed is equivalent to the OR of the complements of the individual variables.
