Previous Year Question (PYQs)
. Match List I with List II
Choose the correct answer from the options given below:
| List-I | List-II |
|---|---|
| A. Odd Function | I. NAND Gate |
| B. Universal Gate | II. XOR Gate |
| C. 2421 Code | III. Amplification |
| D. Buffer | IV. Self-complementing |
Solution
Odd function means output is $1$ when odd number of inputs are $1$. This is the property of XOR gate. So, $A-II$.NAND gate is a universal gate because any logic circuit can be made using only NAND gates. So, $B-I$.
$2421$ code is a self-complementing code. So, $C-IV$.
Buffer is used for amplification or increasing driving capability. So, $D-III$.
Final matching is $A-II,\ B-I,\ C-IV,\ D-III$.
