Noise suppression has become an important issue, particularly with regard to electromagnetic interference (EMI) and electromagnetic compatibility (EMC). Most electric and electronic devices—such as motors, power supplies, and microprocessors generate some degree of high-frequency electromagnetic noise. Although a common issue, the noise produced can prove to be problematic, especially in critical operations, as it degrades the quality of signal and power transmissions. Electromagnetic interference (EMI) filters are one solution to mitigate the effect of electromagnetic noise on power and signal lines. By using the devices in their electrical and electronic equipment, they enhance system performance by redirecting and reducing the noise by canceling or grounding the line.
