Logic Gate And Output
Mediumphysics
AND gate output is high only when?
Select the correct option:
Solution
Incorrect! Answer:
All inputs high
- Boolean Logic: The AND gate performs a logical multiplication (Y=A⋅B).
- Truth Table:
- 0⋅0=0
- 0⋅1=0
- 1⋅0=0
- 1⋅1=1
- Analysis: The output is '1' (High) only when all inputs are '1' (High).
- Circuit Analogy: Similar to two switches in series; the lamp turns on only if both switches are closed.
