Which of the following gates will give an output ' 1 ' for the given inputs?
Which of the following gates will give an output ' 1 ' for the given inputs?
II and III
I and IV
I and III
II and IV
Solution
(I) NAND gate gives output ' 0 ' when inputs are 1,1
(II) NOR gate gives output ' 1 ' when inputs are 0, 0
(III) NAND gate gives output ' 1 ' when inputs are 0,1
(IV) EX-OR gate gives output ' 0 ' when inputs are 1,0
$\therefore$ Ans. II and III
