Where is emi used in?

EMI, or electromagnetic interference, is commonly encountered in electronic devices and systems, affecting the performance of radiOS, televisions, computers, and telecommunications equipment. It can occur in various environments, including industrial settings, urban areas with dense electronic activity, and even within home appliances. EMI can disrupt signals, leading to degraded performance or malfunction, so measures like shielding, filtering, and proper grounding are often implemented to mitigate its effects.
