Question 365Electricity & Electronics - Assistant Engineer

The correct answer is B) OR gate. The four diagrams in the illustration EL-0227 represent the logic circuit symbol for an OR gate. An OR gate is a digital logic gate that outputs a high (1) signal if one or more of its inputs are high (1). This matches the behavior shown in the diagrams, where the output is high (1) if one or more of the inputs are high. The other answer choices are incorrect because a NOR gate outputs a high signal only when all inputs are low, an AND gate outputs a high signal only when all inputs are high, and a NAND gate outputs a low signal when all inputs are high.
