Part 1: • • Analysis of Sequential Circuit Using ... • What is the State Diagram? • The first stage in creating a finite state machine is to figure out how many states are required and which transitions between them are possible. This task does not have a set procedure. The machine’s purpose must be carefully considered by the designer. Selecting a starting state, which is the state that the circuit should enter when power is first turned on or when a reset signal is provided, is a good place to start. • Let’s pretend that state A is the beginning point for our case. The circuit does not need to do anything as long as the input w is 0, hence each active clock edge should keep the circuit in state A. When w equals 1, the machine should notice and change to state B. After w has equaled 1, this transition occurs on the next active clock edge. • Because it has not yet seen w = 1 for two consecutive clock cycles in state B, the circuit should hold the value of output z at 0. If w is 0 on the next active clock edge while in state B, the circuit should return to state A. If w = 1 in state B, the circuit should shift to a third state, C, and generate an output z = 1. As long as w = 1 and z = 1 are maintained, the circuit should remain in state C. • Click below for reading the complete post: • https://eevibes.com/digital-logic-des... • #StateDiagram #SequentialCircuit #DigitalElectronics #CircuitDesign #StateMachine #ElectronicsTutorial #EngineeringEducation #DigitalCircuits #SequentialLogic #CircuitAnalysis #ElectronicsBasics #TechEducation #CircuitDesignTutorial
