What is the reason for using a twisted wire pair for the data backbone on J1939 buses?
A) reduces surface area on which electromagnetic interference can act
B) increases the surface area available for electromagnetic transmission
C) increases the overall toughness of the wire
D) reduces the transmissions speeds of data packets to an acceptable level

Question

Quizplus · Accepted Answer

Twisted wire pairs are used to reduce the surface area on which electromagnetic interference (EMI) can act, thereby minimizing the impact of EMI on the data signals transmitted through the wires. This is crucial for maintaining the integrity of data communication in environments with potential electrical noise.
