The ordered sequence of events in a given sequence diagram is as follows: Place an order. Example: Show the state diagram of following circuit: Show the state diagram of following circuit Circuit, State Diagram, State Table More ExampleMore Example: Binary Counter: Binary Counter – show state diagram and tableshow state diagram and table Because this example is simple, and contains no parallel actions or states, it wouldn’t make sense to use both … A choice pseudo-state is shown as a diamond with one transition arriving and two or more transitions leaving.
