Boolean Functions

Definition

Boolean functions are mathematical functions that take binary inputs and produce a binary output, typically expressed in terms of logical operations like AND, OR, and NOT. These functions serve as the foundation for digital logic design and are crucial for understanding how systems process binary data. In the context of optical computing, Boolean functions enable the representation and manipulation of information through light-based circuits, linking them to the operation of optical systolic arrays and cellular automata.
