Digital logic is a branch of electronics that deals with the manipulation of binary values, typically represented as 0 and 1. It forms the foundation of digital circuits, which are used in devices like computers and smartphones. Digital logic uses logical operations such as AND, OR, and NOT to process information, enabling complex computations and decision-making. At the core of digital logic are logic gates, which are the building blocks of digital circuits. These gates perform basic functions and can be combined to create more complex systems, such as adders and multiplexers. Understanding digital logic is essential for designing and analyzing electronic systems.
