Electromagnetic interference (EMI), or electrical noise, is generated by everything from cellphones to solar flares and can make accurate signal transmission as difficult as trying to have a clear conversation in a noisy room. To improve signal clarity in electronic circuits, device designers turn to EMI suppression filters.
