Questions and Answers
What are logic gates?
Electronic switches which correspond to the operators of Boolean algebra.
Why is it important to represent a formula of Boolean logic in its simplest form?
So it can be implemented efficiently as a circuit.
How do you use Karnaugh maps?
Get adjacent 1's, groups of powers of 2. For variables that remain constant, modify them (by adding NOT) so they give a value of 1, then take the product of them. Do this for all groups of adjacent 1's, add the groups of products.

Study Notes
Logic Gates
- Electronic switches that correspond to Boolean algebra operators.
Importance of Simplifying Boolean Logic
- Simplified formulas enable efficient implementation in circuit design.
Using Karnaugh Maps
- Identify groups of adjacent 1's in powers of 2.
- For constant variables, modify them by using NOT to yield a value of 1.
- Combine the modified variables to form products for all groups of adjacent 1's.
- Sum these products to finalize the formula.
Adjacency in Karnaugh Maps
- Adjacency extends to include wrapping around the edges of the map, enhancing the grouping potential.
Fully Simplifying Boolean Expressions
- Factor out common terms using brackets to reduce the number of necessary logic gates in the circuit.
Marking Unused Values
- In truth tables and Karnaugh maps, unused values can be designated with an 'x'.
Binary Coded Decimal (BCD)
- BCD represents binary numbers using a Boolean formula.
- In BCD, a binary 0 is represented by a variable, while a binary 1 is represented by its NOT counterpart.
- The product follows the order of bits shown in the decimal representation.
