E7 Let B 0 1 consist of the bits 0 and 1 Show that B is a Boolean algebra i e that the bits 0 and 1 form a two element Boolean algebra As said before a logic circuit can be designed using elementary gates where the output from an AND gate or an OR gate or a NOT gate is used as an input to other such gates in tlie circuitry The different levels of voltage in these circuits starting from the input lines move only in the direction of the arrows as shown in all the figures given below For instance one combination of tlie three elementary gates is shown in Fig 9 Fig 9 A logic circuit of elementary gates Now let us try to see the connection between logic circuits and Boolean expressions We first consider the elementary gates For a given pair of inputs x and x2 the output in the case of each of these gates is an expression of the form x A x2 or x V x or x Next let us look at larger circuits Is it possible to find an expression associated with a logic circuit using the symbols A V and Yes it is We will illustrate the technique of finding a Boolean expression for a given logic circuit with tlie help of some examples But first note that the output of a gate in a circuit may serve as an input to some other gate in the circuit as in Fig 9 So to get an expression for a logic circuit the process always moves in the direction of the arrows in the circuitry With this in mind let us consider some circuits Example 7 Find the Boolean expression for the logic circuit given in Fig 9 above 1 Solution In Fig 9 there are four input terminals Let us call themi X1 X2 X3 and x4 So x and x2 are inputs to an OR gate wliicli gives X V x2 as an output expression see Pig 9 a Similarly the other two inputs x3 arid x4 are inputs to an AND gate They will give x3 A x4 as an output expression This is in turn an input for a NOT gate in the circuit So this yields x3 Ax4 as the output expression Now both the expressions x V x2 and x3 Ax4 are inputs to the extreme right AND gate in the circuit So they give x V x2 x3 x as the final output expression which represents the logic circuit X1 X X3 X1 V X X3 X4 X3 X4 Fig 9 a x V X X X Boolean A

C 4 5 Let us consider an example of how to obtain the CNF of a Boolean expression Example 5 Obtain the CNF of the Boolean expression X X1 X2 X3 x1 AX2 x X3 Solution We have x A X2 x V x2 x V x VO x V x V x3 x3 x V x2 V x3 A x V x2 V x3 Similarly you can check that x A x3 x1 V x2 V x3 A x V x2 V x3 Thus the required CNF of the expression X X X2 X3 given here is x V x2 V x3 A x V x2 V x3 A x1 V x2 V x3 A x1 V x2 V x3 Try the following exercise now E3 Obtain the CNF of the Boolean expression X X1 X2 X3 x x V x A x3 As we have said earlier in the context of simplifying circuits we need to reduce Boolean expressions to simpler ones Simple means that the expression has fewer connectives and all the literals involved are distinct We illustrate this technique now Solution a Here we can write xi A x2 A xi A x 2 Example 6 Reduce the following Boolean expressions to a simpler form a X X1 X2 x AX2 x1 x b X X1 X2 X3 x AX V x1 Ax2 AX3 V X1 X3 xi A x2 x1 Ax2 x1 X2 X2 X1 A X2 A x x A O 0 b We can write xi A x2 V x1 A x2 A x3 V x1 A X3 X1 x V x2 AX3 x1 AX3 X1 x V x x2 V x3 x1 AX3 x1 IA x2 V x3 A X1 AX3 De Morgan s Law Identity law Complementation law Distributive law Thus in its simplified form the expression given in a above is O i e a null expression X1 A X2 V X3 X1 AX3 x1 AX2 V x1 AX3 X1 AX3 AD X1 A x2 AX3 V X3 x1 AX3 x1 A X2 AX3 V x1 X3 Complementation la Identity law Distributive law x1 AX2 A XI A X3 V x1 A X3 A X1 A x3 Distributive law Idemp assoc law Distributive law Associative law Absorption law Associative law Complementation law Identity law Distributive law Distributive law Absorption law Thus the simplified form of the expression given in b is x Ax3

involving exactly k variables For instance the Boolean expression in 2 variables X x1 x2 x Ax V xi x V x A X2 is in DNF because it is a join of three minterms namely x Ax2 x1 Ax2 and x A x2 where each one of these involves exactly two variables Observe that each minterm in a DNF should involve all the k variables in the expression X x1 x2 xk k 2 For instance the Boolean expression X X1 X2 X3 x A x2 V x A X2 A X3 is not in DNF because x A x2 is not a minterm of all the three variables However since we can write x Ax x AX2 AI and so the expression X x1 x2 X3 with this change for x A x2 is in the disjunctive normal form Indeed using similar techniques any Boolean expression 0 can be written in disjunctive normal form Let us work out an example to illustrate this technique Example 4 Obtain a disjunctive normal form for the expression X X1 X2 X3 x1 AX V XI AX3 Solution We can write x x2 x x I Also x A x2 A X3 V x3 x x x3 V x AX2 x3 X1 X3 x A x A x3 V x3 x A X A x3 V x A X2 A x3 by Identity law by Complementation law by Distributive law X A X3 A I x1 A X3 A x2 V x k Why don t you try an exercise now Identity law Complementation law Distributive law x1 A X3 A x2 V x1 A X3 AX2 by Distributive law x1 A X2 A x3 V x1 A X2 A x3 by commutativity of A Hence the required disjunctive normal form of the given expression X X1 X2 X3 in three variables is given by x A X2 A x3 V x A x2 A x3 V x1 A X2 A X3 V x A X A X3 by Identity law by Complementation law E2 Obtain the disjunctive normal form of the Boolean expression X X1 X2 X3 x V x V x A Xa The conjunctive normal form is another important type of expression which is analogous to the concept of DNF Definition A Boolean expression in k variables is said to be in conjunctive normal form CNF in short if it is a meet of maxterms each of which involves all the k variables For instance the Boolean expression X X1 X2 X3 x V x2 V x3 x V x2 V x3 x V x2 V x3 is in CNF because it is the meet of maxterms x1 Vx2 Vx3 xVx2 Vx3 and x V x2 V x3 Note that all 3 variables are involved in each maxterm Boolean Al
