I'm struggling with writing the truth table for this state diagram for jk flip flops

The state transition diagram (STD) from your post is simply outlining the possible states, the outputs for each state and the transition conditions possible between the states. In the posted STD, there are 4 states, S0, S1, S2 and S3. That means the system can be in any of state...
Difference between event and guard uml modeling
An event is an action that has been launched or something Close. An event is simply something that has happened. Like a train arriving at the station, a light switch being turned on, or (in line with the season) Santa popping down the chimney. a guard is just a...
State Machine Diagram - Transition from all states
Both solutions would be appropriate, depending on their legibility on the diagram. Too many transitions tend to clutter a diagram and make it difficult to read. So if you have just a few source states (say less than 4), using transitions to a junction pseudostate (not a join pseudostate -...
How to construct a State Diagram for a Class?
oop,uml,state,diagram,state-diagram
You can't derive state diagram from a class diagram. For behaviour is not defined by structure. But you can create a state diagram for explanation in addition to a class diagram. Principally your state diagram is OK. But: you have obvious errors in its lower part - you are...
What is the corret use of use case diagram
I guess the UC in #1 should read "item selection" and not section. Both of your designs are wrong in the one or other way. "item selection" is not a use case. It does not deliver any value to Actor (at least none I could imagine). So you are trying...
