Definition
An OR circuit, also known as an OR gate, is a basic logic gate in digital electronics. It outputs a "true" (1) signal if any of its inputs are "true" (1). Think of it as a decision-maker: if one or more conditions are met, it acts. OR circuits are fundamental to building complex digital systems, like computers and smartphones. Unlike an AND circuit, which requires all inputs to be true, an OR circuit only needs one. Itβs a core building block of digital logic.
