Brief information about OR logic gate
The OR logic gate is one of the fundamental building blocks of digital logic circuits. It operates on two binary inputs and returns true if at least one of the inputs is true. In logical expression, it can be denoted by the “+” symbol and follows the basic rule that if either or both inputs are “1”, the output is “1”; if both inputs are “0”, the output is “0”.
History of the Origin of the OR Logic Gate and the First Mention of It
The history of the OR logic gate can be traced back to the early 19th century when mathematicians and logicians began formalizing Boolean Algebra. George Boole’s 1854 work “An Investigation of the Laws of Thought” laid the foundation for the OR logic operation, though it wasn’t implemented in physical form until later.
The actual implementation of OR gates in electronic form began with the advent of relay-based logic in the early 20th century, followed by the development of semiconductor-based gates with the advent of the transistor in 1947.
Detailed Information About OR Logic Gate. Expanding the Topic OR Logic Gate
The OR logic gate serves as an essential function in computational logic. Its symbolic representation is often a curved ‘D’ shape with two inputs and one output.
Truth table for OR gate:
| A | B | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
The Internal Structure of the OR Logic Gate. How the OR Logic Gate Works
The internal structure of an OR logic gate can be implemented using different technologies like diodes, transistors, or even mechanical switches. In a typical OR gate using transistors, two transistors are connected in parallel, and the output is taken from their common connection point. If any input is high, at least one transistor is on, allowing current to flow, and the output will be high.
Analysis of the Key Features of OR Logic Gate
- Commutativity: A OR B = B OR A
- Associativity: (A OR B) OR C = A OR (B OR C)
- Identity Law: A OR 0 = A
- Domination Law: A OR 1 = 1
- Complementarity: A OR (NOT A) = 1
Types of OR Logic Gate. Use Tables and Lists to Write
There are variations in OR gates based on the number of inputs and technology used.
- 2-Input OR Gate: Standard OR gate with two inputs.
- Multi-input OR Gate: More than two inputs.
| Technology | Types of OR Gates |
