State Diagram

Sequential Circuits can be described pictorially via the state diagram.

The state diagram illustrates several things:

  • Possible states of the sequential circuit,
  • Possible transitions between states (which depend on the inputs);
  • Circuit output values (which depend on the state, inputs, or both)

Use cases:

  • Detect a sequence of strings
