If the output of a 2-input NAND gate is fed as the input to a NOT gate, () name the new  logic gate obtained and (ii) write down its truth table.                                     

Answer:

                   

Inputs		Output of NAND gate	Output of NOT gate
A	B	\[\Upsilon '=\overline{A.B}\]	\[\Upsilon =\overline{\Upsilon }'\]
0	0	1	0
0	1	1	0
1	0	1	0
1	1	0	1

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