  • The conventional state diagram for a synchronous sequential circuit places the circuit's output labels on arrows representing state transitions. This notation leads students to think that the labels denote output values during, or associated with, changes of state; in fact, the output is not defined when the state is changing. The misconception fostered by this notation creates difficulties for students when they encounter real circuits. A state diagram is proposed which clarifies signal timing… CONTINUE READING
