High-Speed CAN bus topology. Most digital buses are driven high to represent a logic 1 and low to represent a logic 0. This is not the case with the CAN bus, that adopts a state called recessive, describing 1's, and a state called dominant, signifying 0's. In the recessive state, the termination resistors determine the bus voltages.
