De Morgans Theorem

De-Morgan's First Theorem

As per De-Morgan's first theorem, the complement outcomes of the AND operation are equivalent to the OR operation of the complement of that variable. Thus, it is equivalent to the NAND function and is a negative-OR function manifest that (A.B)' = A'+B' and we can show this using the given table.

De-Morgan's Second Theorem

As per De-Morgan's second theorem, the complement outcomes of the OR operation are equivalent o the AND operation of the complement of that variable. Thus, it is the equal of the NOR function and is a negative-AND function that manifests that (A+B)' = A'.B' and we can represent this using the given truth table.
