Just as is done is algebra Notice that Boolean addition defined here on {0,1} is NOT the same as the addition on the set of integers modulo 2 14 Example 141 Example 141 The following functions are equivalent (1) F(x,y) = xy (2) G(x,y) = xy xy xy Proof We show the two functions have the same values for every possible orderedSince a maximum number of terms possible = 2 n, so we choose half of the terms ie 2 n / 2 = 2 n1Distributive laws of Boolean algebra state that (i) X(Y Z) = XY XZ (ii) X YZ = (X Y)(X Z) 1 stlaw X(Y Z) = XY XZ holds good for all values of X, Y and Z in ordinary algebra whereas X YZ = (X Y)(X Z) holds good only for two values (0, 1) of X, Y and Z 14 Express in the Product of Sums form, the Boolean function F(x, y

The most widely used theorems to solve the Boolean algebra are De Morgan's Laws These are of two types De Morgan's First Law and De Morgan's Second Law First law of De Morgan (x y)' = x' y' It states that the sum of their individual complement of a variable is equal to the complement of product of variableBoolean Algebra and Logic Gates cs309 G W Cox – Spring 10 The University Of Alabama in Hunt sville Computer Science Boolean Algebra The algebraic system usually used to work with binary logic expressions sville Computer Science Implementing a Boolean expression as a 12 Boolean Functions • A Boolean function is a function whose arguments, as well as the function itself, assume values from a twoelement set ({0, 1)}) • Example F(x, y) = x'y' xyz x'y • After finding the circuit inputs and outputs, you can come up with either an expression or a truth table to describe what the circuit does
Boole's Intuition Behind Boolean Logic Variables X, Y, represent classes of things No imprecision A thing either is or is not in a class If X is "sheep" and Y is "white things," XY are all white sheep, XY = YX and XX = X If X is "men" and Y is "women," XY is "both men and women," XY = Y X and XX = X If X is "men," YTranscribed image text Huntington's Postulates • All properties of Boolean algebra can be proved from these properties xy = yX x (y z) = (x y) (x 2) x1 = x x y = y x x (y z) = (x y) (x 2) X0=X xx=0 xx=1 • We call these properties from which we derive the others axioms or postulates • Huntington's postulates are satisfied by the basic operators we have defined– Twovalued Boolean algebra is developed in a formal mathematical manner – This formalism is necessary to develop theorems and properties of Boolean algebra 11 Duality Principle • An important principle – x(x'y) = xy and xx' y = (xx')(xy) = xy
