Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...

For years now, government institutions have beenregulating the amount of EMI (electromagneticinterference) an electronic device or system canemit. Their efforts primarily target lowering ...

As an engineer, you know how fast consumer electronics devices operate and how many tasks they perform in fraction of second. High-speed operation of these devices has made possible the many pleasures ...

[Michael Ossmann] spoke on Friday to a packed house in the wireless hacking village at DEF CON 25. There’s still a day and a half of talks remaining but it will be hard for anything to unseat his ...

Frequency spread spectrum (FSS) is a technique that’s been widely used in power-conversion designs to reduce electromagnetic-interference (EMI) noise. But optimizing EMI without compromising on other ...
