Title: Describe DeMorgan’s theorem.
Course: Mechatronics III (13901-III) > Section: Understanding Programmable Logic Controller Systems

Description should state that the theorem says any logical binary expression remains unchanged if we

- change all variables to their complements
- change all AND operations to OR operations
- change all OR operations to AND operations
- take the complement of the entire expression.

Description also should state that the theorem is useful in basic gate operations, particularly NAND and NOR gates.

Process/Skill Questions:

- How is DeMorgan’s theorem applied in basic gate operations?
- How are variables changed to their complements?
