  10. Figure 5-7 RZ Encoding

  11. Bifase (Auto-Sincronizados) • Siempre hay una transición a mitad del intervalo de duración del bit. • Técnicas • Manchester: La transición de mitad del intervalo sirve para sincronización y transmisión de datos. • Manchester Diferencial: La transición de mitad del intervalo solo sirve para sincronización
