+//Caption: To verify that AND-OR topology is equivallent to NAND-NAND system

+disp('In digital electronics we have to come across situations where we need to use an inpout with a bar but here we will denote as');

+disp('X with a bar = Xb and X with two bars = Xbb');

+

+//Solution

+disp('We know that X =Xbb');

+disp('For AND OR logic the output of AND and simultaneously neglecting the input to following OR does not change the logic');

+disp('We have also neglected the output of the OR gate and at the same time have added an INVERTER so that logic is once again unaffected');

+disp('AN OR gate neglected at each terminal is an an AND circuit');

+disp('Since AND followed by an inverter is NAND ');

+disp('Hencee the NAND NAND is equivallent to AND OR');
