Differential mode und Common mode im CAN-Bus

[sommer (Gast)]

Hi,

In meinem CAN-Buch steht

For CAN networks obviously a DC path of 120 Ohm // 120 Ohm = 60 Ohm for
dominant signals must be provided. The location of the terminating
resistors should not matter at the moment. These line terminations are
valid only for the differential mode signal, since the common mode
signal is not properly terminated.

Kann mir jemand erklären, was der Autor damit meint?
Differential mode = dominant bit?
Common mode = recessive bit?

Danke im Vorraus
