1 ) In XOR gate , the output is zero , if inputs are . . . . . . . . . . : - A ) same , B ) different , C ) may be same or different , D ) None of these ,

1 ) In XOR gate , the output is zero ,  if inputs are . . . . . . . . . .  : -

Choose single option from these following : -

A ) same ,                                                B ) different ,

C ) may be same or different ,                 D ) None of these ,

Correct Answer : -  A ) same ,

Explanation : -

 

2 ) In XOR gate , if we have different inputs , so output will be . . . . . . . . . . . : -

Choose single option from these following : -

A ) 0  ,                                              B ) 1  ,

C ) infinite  ,                                     D ) None of these ,

Correct Answer : -   B ) 1  ,

 

3 ) 

The NAND gate as shown in figure ,  if X is 1 , so Y will be : -

Choose single option from these following : -

A ) 0 ,                                               B ) 1 ,

C ) infinite ,                                      D ) None of these ,

Correct Answer : -  A ) 0 ,

Explanation : -

As by diagram , the both inputs will be similar because they are connected by X , So we will get such type of table : -

 If  X = 1 , So Y will be 0 ,

And if  X = 0 , So Y will be 1 .

 

4 ) 

If  X = 0 and  Y = 1 , So Z will be . . . . . . . . . . . . . . ?

Choose single option from these following : -

A ) 0 ,                                               B ) 1 ,

C ) infinite ,                                      D ) None of these ,

Correct Answer : -    B ) 1 ,

Solution : -
