The product-of-sums form is also called as Conjunctive Normal Form as the sum terms are ANDed together and Conjunction operation is logical AND. When two or more sum terms are multiplied by a Boolean OR operation, the resultant output expression will be in the form of product-of-sums form or POS form. Here the sum terms are defined by using the OR operation and the product term is defined by using AND operation. Such an expression is called a Product of Sum expression or POS in short. Judging by the algebraic expression, it is evident that the expression is a product of sums.

Follow up the examples below to learn how to map those values. The above implications bring us to a conclusion that there can be 2^(number of variables) number of combination for a single boolean expression. Implies you need to evaluate the value of expression for each and every Truth value of a variable. Suppose there is only one variable, it implies that it can hold either ‘true’ or ‘false’ but, when there are two variables then you can have a combination of (T -> True, F -> False). The main point is to evaluate the value of Boolean expression for each and every combination of the Truth values of
Now truth values of a variable are either ‘true’ or ‘false’. Truth Table is formed by evaluating the Boolean expression for each and every truth value of a variable. Follow up to know How?Įxample : Shorthand notation representing the boolean expression / F(A,B) = A + B //This is a boolean function comprising of variables A and B F(A, B, C) = A(B + C(A + B)) \ Boolean Expression Truth table formation You can represent any boolean expression in form of a Truth Table. The shorthand notation for a boolean function is that it is represented with a capital F followed by parenthesis comprising of all variables of that equation separated by comma(‘,’). The value of variables may or may not be pre-defined. Any equation with the mixture of these two components forms a Boolean function. Methods to simplify the boolean functionīoolean Functions are comprised of two components i.e., Variables and Logic operations(AND, OR, NOT…etc).Try the interactive truth table generator.Conversion from minimal to canonical forms.This site uses Just the Docs, a documentation theme for Jekyll.
