What is EMI known to cause?

EMI, or Electromagnetic Interference, is known to disrupt the normal operation of electronic devices and communication systems. It can cause various issues, primarily resulting in the malfunction of components. This interference can occur from a variety of sources, such as power lines, motors, electronic circuits, or other nearby devices producing electromagnetic fields.

When EMI is present, it can introduce noise into the signal being transmitted, distort the information being processed, or lead to data loss. This is why understanding the impact of EMI is crucial for ensuring the reliability and performance of communications systems. It’s vital for installers to recognize the potential for EMI in their work environments, as mitigating its effects is essential for maintaining the integrity of the systems they install.

The other options describe scenarios that don’t accurately represent the implications of EMI. Signal enhancement, increased frequency, and better performance are not outcomes associated with EMI; instead, they imply improvements or advantages in a communication system, which EMI can hinder rather than facilitate.
