Study Notes
K-Maps in Digital Logic Design
- The main purpose of using K-maps in digital logic design is to simplify complex Boolean algebraic expressions and to visualize the relationships between variables.
K-Map Cell Definitions
- In a K-map, adjacent cells are defined as cells that have only one variable different between them.
K-Map Cell Representation
- A cell in a K-map can represent up to one 2^2 (or 2^N) possible values of N variables.
Digital Logic Pioneers
- George Boole is credited as the brain-child of digital logic.
- Gottfried Wilhelm Leibniz refined the binary number system and established its principles of arithmetic and logic.
- Charles Sanders Peirce described how logical operations could be carried out by electrical switching circuits in an 1886 letter.
- Walther Bothe invented the first modern electronic AND gate in 1924.
Early Computing Era
- Mechanical analog computers were first used for astronomical calculations in the ancient era.
