What is the primary purpose of twisting wiring pairs?

The primary purpose of twisting wiring pairs is to reduce electromagnetic interference (EMI). Twisting the pairs together helps to cancel out the electromagnetic fields that can be generated by nearby wires or electronic devices. When the two wires in a pair are twisted, they experience similar amounts of interference, which can be effectively canceled out, leading to clearer signals and improved performance in data transmission. This technique is particularly vital in communication cables, such as twisted pair cables, which are widely used in networking and telecommunication systems to maintain signal integrity over distances. The design minimizes the pickup of external noise and ensures that the data being transmitted is protected from degradation, leading to more reliable and efficient communication.
