What is electromagnetic interference and what causes it? The main approaches to filtering out EMI and reducing its impact. How to evaluate EMI filters and what to know about designing them.

We’ve always been fascinated by things that perform complex electronic functions merely by virtue of their shapes. Waveguides come to mind, but so do active elements like filters made from nothing but ...

All too often, designers spend so much time focusing on the specification and selection of their complex, higher cost devices, such as processors, FPGAs, and ADCs, that they don’t fully take into ...

For the past couple of years, I’ve been using AI to assist in the design of my hardware and firmware projects. The experience has generally been good, even though the outcome isn’t always useful. So, ...

Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...

This analytical and graphical technique allows engineers to determine, in closed form, the output of an RC filter driven by a PWM pulse train. It is based on the principle that current and voltage ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...
