Question

For the gate shown in the figure, the output will be HIGH 

• A. If and only if both the inputs are LOW
• B. If and only if both the inputs are HIGH
• C. If one of the inputs is HIGH
• D. If one of the inputs is LOW

Hint:

For an OR gate, the output is HIGH if at least one input is HIGH.

Answer 1

The Correct Option is C

Step 1: Determine Gate Type.
The provided circuit component is an OR gate. This gate's output is HIGH if at least one input signal is HIGH.

Step 2: Evaluate Options.
- (A) Exclusive if both inputs are LOW: Incorrect. An OR gate outputs LOW solely when all inputs are LOW. - (B) Exclusive if both inputs are HIGH: Incorrect. An OR gate outputs HIGH even if only one input is HIGH. - (C) If at least one input is HIGH: Correct. An OR gate produces a HIGH output if either input is HIGH. - (D) If at least one input is LOW: Incorrect. An OR gate will still output HIGH if one input is HIGH, regardless of the other input's state.

Step 3: Final Determination.
Option (C) is the accurate description, as an OR gate yields a HIGH output when one or more of its inputs are HIGH.
