Spectrum Control Inc., introduced a family of modular power EMI filters bringing high performance and design flexibility to a variety of MIL-STD-461 designs with SWaP-C requirements.

Astrodyne TDI introduced the latest DIN-rail mount EMI/EMC filter line, specially designed for industrial and medical applications that require a highly compact solution

This article presents a quick and easy simulation model for filter performance analysis. The simulation model that the author built matches the test results quite well and it can serve as a useful and powerful tool for electronics design engineers.

“There are two kinds of engineer, those who are building antennas on purpose and those who are not doing it on purpose.” Every oscilloscope ships with at least two 10x probes. They are ubiquitous in every lab. But they have a significant problem above 10 MHz, unless care is taken. In some cases, we can turn this problem into a feature.

I have lost count of the number of times I have been asked to fix an EMC problem, only to find that a shielding box has been designed or purchased to provide XdB up to fMAX. Or a filter has been designed or purchased with a similar specification, but to reduce cost the filter has been mounted on a printed circuit board (PCB) inside the box, with a cable from it entering or exiting the box through a plain connector.

Eric Bogatin explains the figures of merit in the time and frequency domain, and he steps through how to get a rough measure of the highest frequency components in a signal.
