Question

Construct a truth table for the logical operator NAND.

Answer 1

Answer with Step-by-step explanation:

We are given that NAND

We have to construct the truth table for the logical operator NAND

AND =$A\cdot B$

NAND=$\bar{A\cdot B}$=Opposite to $A\cdot B$

It means if $A\cdot B=0, \;then \;NAND=1$

If $A\cdot B=1$ then, NAND=0

NAND=$\bar{A\cdot B}$

If A=0 and B=0 then $A\cdot B=0$

Output in NAND=1

If A=0 and B=1 then $A\cdot B=0$

Output in NAND=1

If A=1 and B=0 then $A\cdot B=0$

Output in NAND=1

If A =1 and B=1 then $A\cdot B=1$

Then, output in NAND=0
