If the output of a 2-input NOR gate is fed as the input to a NOT gate (i) name the new logic gate obtained and (ii) write down its truth table.   

Inputs		Output of NOR Gate	Output of NOT Gate
A	B	\[\Upsilon '=\overline{A+B}\]	\[\Upsilon =\overline{\Upsilon }'\]
0	0	1	0
0	1	0	1
1	0	0	1
1	1	0	1

 

Answer:

                    As\[\Upsilon =A+B,\] so the new logic gate obtained is an OR gate.
