1. An XOR gate produces an output only when its two inputs are
- A. high
- B. high
- C. high
- D. high
Answer: Option C
Explanation:
An XOR gate produces an output when its two inputs are different. The output is high (1) if one input is high and the other is low, but the output is low (0) if both inputs are the same (both high or both low).
- Inputs are different (0) and (1): Output is (1)
- Inputs are the same (0) and (0) or (1) and (1)): Output is (0)
