Today we live in a hyper-connected world, surrounded by smart products. If industry forecasts are correct, by 2020 — just 2 short years from now — there will be over 28 billion internet-connected devices. Beyond smart phones and autonomous vehicles, smart cities, smart factories, and smart homes are also quickly emerging as promising opportunities that could help improve how we live, work and play.
While these new capabilities will be a delight to us as consumers, they are a nightmare for engineers and product designers. With hundreds of sensors, microprocessors, and wired and wireless communication components, engineers face immense challenges in ensuring reliability and performance. In the complex web of electronic circuitry, something, somewhere that is left unaddressed could lead to failure. One of the big challenges confronting product designers is electromagnetic interference, or EMI.
