Digital Systems Lab 11

Lab 11: Finite State Machines

Lab 11 will come from the published version of the lab manual.

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 draw the circuit diagrams for questions 1-2 on pages 147-149.
  • Draw the circuit diagram for question 3 on page 150.
  • Note: monostable timer information is on page 173 in lab 13!

Lab Manual Errata

The following are known errors in the lab manual corresponding to this lab.

  • Page 145 part I should say “Moore machines are finite state machines…”
  • Page 150, the state diagram is not correct. See below for the correct state diagram.
  • Page 152, part (e). You must show your work by hand, but you can double check using LogicAid if you want.
  • Page 154, part (e). You must show your work by hand, but you can double check using LogicAid if you want.
