EXPERIMENT 11 (ALGORITHMIC STATE MACHINES)

A lock to a certain safe can be opened with a correct combination. The lock must be supplied with the correct combination within two attempts. Specifications of the lock circuit are as follows:

1) After the first unsuccessful attempt, output message (MSSG).
2) After the second unsuccesful attempt, sound an alarm.
2) When the reset is used; stop the alarm if it is on, or lock the safe if it is open, and reset to allow two more tries.

Your part in this problem is to design the module given in the figure below. Make a detailed design of this module, and realize the controller with JK flip-flops.


IMPORTANT NOTE
Please make sure you demonstrate every aspect of your study (asm diagram, state diagram, state/excitation tables, truth tables, k-map realizations, functions etc.) in laboratory.
