Conversion of Boolean fraction. A Boolean expression can have two types. *Sum of product.(SOP) *product of sum(POS)  In the SOP Boolean expression,different product terms are combined with the addition operators, While POS Boolean expression different sum terms are combined with the product operator.The product in SOP Boolean expression are called minterms, while sum term in POS boolean expression are called maxterm. Simplification of Boolean expression using K-MAP. K-map is a technique of simplify the Boolean  expression using graphical representation method. It simplifying the boolean expression by combining the similar expression and deleting the repeated variable. Input A Input B Output Y 0 0 0 0 1 1 1 0 0 1 1 1 The 0's and 1's written at the top of K-map represent the value of the input variable,A nad B. The value inside the K-Map re...

Logic gate A logic gate is an electronic switch which produces an electrical signal(representing 0 and 1) based one or more input signal using principal of Boolean logic such as AND, OR or NOT. Basic logic gate Basic logic gate are building block of digital circuit  that perform various logical operation such as AND,OR or NOT on binary input. there are following  basic logic gate. AND OR NOT AND gate The AND gate contains two input such as A and B and gives one output Y. In AND logic gate if both input is true then output is true otherwise false.     An AND logic gate can have one or more than inputs.  AND gate  expressed logically.                         Y=A.B Input A Input B Output Y(A.B) 0 0 0 0 1 0 1 0 0 1 1 1   The truth table of AND gate OR gate The OR ...
