Karnaugh maps are a tool used to simplify complex Boolean expressions. To do so you will need to be able to
- Complete a Karnaugh Map for a given Boolean Expression or a given Truth Table.
- Identify the main blocks of 1, 2, 4, 8 or 16 consecutive 1s.
- Use these blocks to write down the Simplified Boolean Expression for your Karnaugh Map.
The following slideshow gives examples of how blocks can be identified on different Karnaugh Maps:
Use a Karnaugh Map with 4 inputs to simplify each of the following Boolean expressions:
