Lab 13: Sequence Detectors
Errata
The fall 2024 version of the lab manual needs the following changes:
- For all three circuits, a separate pushbutton should be used that can asynchronously reset each flip-flop and put the FSM into its reset (00) state.
- In the lab homework, all derived expressions should be minimum.
Suggested Pre-Lab Activities
Completing the following activities before attending lab will save you time during the lab session.
- Assign state assignments, fill out the transition table, and derive expressions for circuits 1-2.
Resources
Watch/read the following resources prior to attending this lab. This information will teach you how to use lab equipment and provide suggestions and technical tips for successfully completing the lab.
- Textbook: Chapter 13
- (Optional) Textbook: Circuit Analysis textbook, Practical Example chapter. (This explains how the 555 timer works in both astable and monostable modes.)
