EMI
Posted on December 19, 2012 by KVMG-CMS | 0 comments
Electromagnetic Interference. Any electronic device gives off an electrical field when it is operating. EMI is when the electrical field of one device interferes with the electrical field of another device. EMI is bad for a signal going through a cable as it can corrupt the signal, so to prevent EMI in a cable, a shield is used. Conversely, the shield also prevents the signal going through the wire from causing EMI in other devices.
