2. If any one input is HIGH (or 1), and output is also HIGH (or 1), such Gate is: [Uttarakhand P.C.S. (Pre) 2021]

Correct Answer: (a) OR Gate
Solution:

The Logic OR Gate is a type of digital logic circuit whose output goes HIGH to a logic level I only when one or more of its inputs are HIGH (or 1).

The output Q of a Logic OR Gate only returns LOW again when ALL of its inputs are at a logic level 0. In other words for a logic OR gate, any HIGH input will give a HIGH, logic level 1 output.

3. The output C of given logic circuit is: [Uttarakhand P.C.S. (Pre) 2021]

Correct Answer: (b) 1
Solution:

Output of A and 1 = 1 (Q₁)

Output of B and 1 = 1 (Q₂)

Output of Q₁ and Q₂ = C = 1
