Correct Option: A

AND gate has more than _____ inputs.

  1. one

  2. two

  3. zero

  4. none of these


Correct Option: A

You should have rejected this option as inputs have to be 2 or more.

The symbol for XOR function is

  1. bar

  2. plus

  3. dot

  4. plus inside the circle


Correct Option: D

The input-output relationship of gates is given by

  1. false table

  2. truth table

  3. table

  4. none of these


Correct Option: B
Explanation:

The input-output relationship of gates is given by truth tables.

An OR gate produces 0 output when both inputs are

  1. 0, 0

  2. 1, 1

  3. 2, 2

  4. 3, 3


Correct Option: A
Explanation:

The truth table of OR gate i |||| |---|---|---| | A| B| C| | 0| 0| 0| | 0| 1| 1| | 1| 0| 1| | 1| 1| 1|

The XNOR function is the complement of

  1. NOT

  2. OR

  3. AND

  4. XOR


Correct Option: D
Explanation:

XNOR stands for Exclusive NOR. Hence, the XNOR function is the complement of XOR function.

The NOR function is the complement of ______ function.

  1. NOT

  2. OR

  3. AND

  4. NAND


Correct Option: B
Explanation:

NOR stands for NOT OR. Hence, NOR function is the complement of OR function.

The NOT gate has _____ output(s).

  1. 0

  2. 1

  3. 2

  4. 3


Correct Option: B

The NAND function is the complement of _____ function.

  1. NOT

  2. OR

  3. AND

  4. NOR


Correct Option: C
Explanation:

NAND stands for NOT AND. Hence, NOR function is the complement of OR function.

The output of AND gate is 1 when both inputs are

  1. 0, 0

  2. 1, 1

  3. 2, 2

  4. 3, 3


Correct Option: B
Explanation:

The truth table of AND gate i |||| |---|---|---| | A| B| C| | 0| 0| 0| | 0| 1| 1| | 1| 0| 1| | 1| 1| 1|
