Which logic gate is AND gate?
A.
When all inputs are high, the output is high.
B.
When all inputs are low, the output is low.
C.
When all inputs are high(logic 1), the output is high, otherwise the output is low(logic 0).
D.
As long as one of the inputs is high (logic 1), the output is high(logic 1); Only when all inputs are low, the output is low.
