4 big benefits have been done so, have been exactly that antijamming capability is good first, because external electromagnetic interference acts on 2 at the same time
On conducting wire (common-mode noise), the value after both subtract each other is constant；Secondly because transmitting the signal of opposite in phase, what 2 conducting wires produced
Electromagnetic field is cancelled out each other, and external electromagnetic interference is small；Furthermore be then because with 2 conducting wire signs alternately as basis for estimation, and
It is non-to be judged using voltage, therefore compare and be not readily susceptible to Part temperature change influence；It is exactly finally the voltage change of differential signal
Amplitude can accomplish smaller, reduction device power consumption.
