What output does an XOR gate produce if both inputs are the same?

An XOR (exclusive OR) gate is designed to produce an output of 1 only when the inputs differ from each other. When both inputs are the same, whether they are both high (1) or both low (0), the XOR gate will output 0. This characteristic makes the XOR gate particularly useful in digital circuits where a comparison function is needed to determine differences between two binary inputs.

Thus, when both inputs are the same, the output is consistently 0, reinforcing the fundamental behavior of XOR gates in digital logic.
