Part 1 of this series described how digital signals propagate through PC boards [Refs. 1, 2, 5, 6]. In part 2, we look at specific board designs to achieve low EMI. The biggest issue I see in my ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...

Rectangular or cylindrical? Comparing the enclosure types. Determining wall thickness. How does the enclosure's orientation impact performance? In Part 1, we covered modal analysis, the Timoshenko ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

In part 1 we reviewed why artificial intelligence (AI) is moving slowly. In short, AI is growing and will continue. Reports which say growth is slow may be looking into specific trends, industries, or ...

After helping clients get their products compliant for EMI, I’ve seen one underlying issue: Poor PC board design. In my experience, IoT product designers run into problems caused by poor PC board ...

What is modal analysis? Evaluating vibration sensor enclosures and their natural frequencies. Determining the most important modes and frequencies with the mode participation factor. A close look at ...
