Frage zu CAN

Hi,

Ein Nominal-bit-time besteht aus Sync-segment,
Propagation-delay-segment, Phase-buffer-segment1 und
Phase-buffer-segment2, wobei Sample-point zw. Phase-buffer-segment1 und
Phase-buffer-segment2 ist. Die Beschreibung lautet:

The CAN protocol regulates bus access by bit-wise arbitration. The
signal
propagation from sender to receiver and back to the sender must be
completed within one bit-time. For synchronization purposes a further
time segment, the propagation delay segment, is needed in addition to
the time reserved for synchronization, the phase buffer segments. The
propagation delay segment takes into account the signal propagation on
the bus as well as signal delays caused by transmitting and receiving
nodes.

Was versteht man unter Nominal-bit-time?
