ECC Test 5 Practice

In an XOR (exclusive OR) gate, the output is high only when the inputs differ; that is, when one input is high and the other is low. When both inputs A and B are high, the XOR gate will produce a low output. This behavior stems from the gate's fundamental logic: it only outputs a high signal (or a 1) when there is one high input and one low input. Therefore, if both inputs are high, the gate recognizes that they are not differing and results in a low output. Understanding this characteristic of XOR gates is crucial for those working with digital logic design and signal processing.
