Draw the logic symbol of the gate whose truth table is given below : 

Inputs		Output
A	B	\[\Upsilon \]
0	0	1
0	1	0
1	0	0
1	1	0.

  If this logic gate is connected to NOT gate, what will be the output when (i) \[\mathbf{A=0,B=0}\] and (ii) \[\mathbf{A=1,B=1}\]? Draw the logic symbol of the combination.        

Answer:

                    The given truth table is for a NOR gate. Its logic symbol is shown in Fig.                                         Logic symbol of NOR gate.

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

                        The combination acts as an OR gate. Its logic symbol is shown in Fig. Logic symbol of OR gate.
