Electromagnetic compatibility (EMC) refers to the ability of electronic devices to operate without causing or being affected by electromagnetic interference. This means that devices can function properly in their intended environment without disrupting each other. For example, a cell phone should work well without interfering with a radio or other nearby electronics. To achieve EMC, manufacturers must design their products to minimize unwanted emissions and enhance their immunity to external interference. This involves testing and adhering to specific standards that ensure devices can coexist in various settings, such as homes, offices, and industrial areas, without causing problems.
