VERIFICATION & REALISATION OF DE MORGAN’S THEOREM

AIM:

To verify De-Morgan‟s theorem for two variables

COMPONENTS AND EQUIPMENTS REQUIRED:

ICs 7400,7402, and IC trainer kit

THEORY:

1.DeMorgantheoremstates that

a) AB’=A’+B’

b) (A+B)’=A’.B’

De-Morgan‟s theorem is highly useful to simplify the Boolean expression

PROCEDURE:

1)Test all the IC packages using digital IC tester.

2)Setup the circuit one by one and verify their truth table.

3)Observe the output corresponding to input combinations and enter it in truth table.

DEMORGAN’S THEOREM:


a)  AB’=A’+B’ 

 

 

b) (A+B)’=A’.B’

  

 

RESULT:
