NOT-IF-THEN gate; NOT-IF-THEN element
A digital logic gate that outputs true only when the first input is true and the second is false; equivalent to A AND NOT B. Used in computing contexts.
A NOT-IF-THEN gate outputs true only when A is true and B is false.
AND gate outputs true only when both inputs are true, while 排他素子 requires the first input true and the second false.
XOR (exclusive OR) outputs true when inputs differ; 排他素子 is a specific case where the output is true only when A is true and B is false.
Compound of 排他 (exclusion) + 素子 (element, device), referring to a logic element that excludes the case where the second input is true.
