Si consideri il seguente modello Modelica. Quale dei seguenti UML state diagram lo rappresenta correttamente ?
block FSA  //  Finite State Automaton

/* connector declarations outside this block:
connector InputInteger = input Integer;
connector OutputInteger = output Integer;
*/

InputInteger u; // external input
OutputInteger x; // state
parameter Real T = 1;
