Study Notes
Karnaugh Map Overview
- A Karnaugh Map (K-map), also known as a Veitch diagram, is a visual representation for simplifying Boolean expressions.
- Introduced by Edward Veitch and modified by Maurice Karnaugh in 1953 for digital logic design.
Structure of Karnaugh Map
- Comprises cells that represent different combinations of input variables from a truth table.
- Each cell corresponds to a row in the truth table, indicating the output for a given input combination.
- Inputs are usually shown on the edges of the map, with one variable along the top and another along the side.
Input and Output Representation
- Binary output values (0s and 1s) from the truth table are placed in corresponding cells of the K-map.
- The arrangement allows for a simplified visual representation, aiding in the identification of patterns for simplification.
Arrangement and Gray Code
- Input values in the Karnaugh Map are ordered as: 00, 01, 11, 10, maintaining a single bit change between adjacent cells, referred to as Gray code.
- This unique ordering helps in simplifying the Boolean expressions by making adjacent cells easier to identify and group.
Simplification Rules
- Adjacent cells can be grouped to eliminate variables according to Boolean algebra principles (Postulate 6a).
- Groups must consist of cells that contain the same output value (either all ones for Sum of Products (SOP) or all zeros for Product of Sums (POS)).
- Cells with different values cannot be included in the same group.
Practical Application
- Karnaugh Maps are widely used for simplifying logic functions, thereby facilitating easier design and analysis in digital circuits.
