The OR gate is a digital logic gate that implements logical disjunction. The OR gate outputs "true" if any of its inputs is "true"; otherwise it outputs "false". The input and output states are normally represented by different voltage levels.
The OR gate is known as a primitive digital electronics building block in digital logic. This is one of the logic gates that executes the logical disjunction—a function producing true when at least one input is true. OR gates can be used in applications in digital circuits, computer systems, and other electronic devices.
OR Gate Definition: An OR gate is defined as a logic gate that outputs high (1) if one or both inputs are high (1). Working Principle: The working principle of an OR gate is to find the maximum between binary digits, resulting in a high output if any input is high.
An OR logic gate is a very simple gate/construct that basically says, "If my first input is true, or my second input is true, or both are true, then the outcome is true also." Note how we have two inputs and one output. This isn't the case for all logic gates.
The Logic OR Gate is a type of digital logic circuit whose output goes HIGH to a logic level 1 only when one or more of its inputs are HIGH. The output, Q of a “Logic OR Gate” only returns “LOW” again when ALL of its inputs are at a logic level “0”.
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR and XNOR. The AND gate is named so because, if 0 is false and 1 is true, the gate acts in the same way as the logical "and" operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate.
In summary, the AND gate and the OR gate are two essential logic gates with distinct functionalities, truth tables, applications, and implementation methods. The AND gate outputs a high signal only when all inputs are high, while the OR gate outputs a high signal if any input is high.
