One of the most fundamental concepts in our profession is impedance. Due to the nuances of the mathematics related to this quantity, the minutia of what is taking place and the associated nomenclature ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. What you’ll learn: Plot complex impedances on a Smith chart. Determine SWR from the Smith chart. Determine the ...

Ohms are one of the specs that both speaker and receiver manufacturers use to give you an idea about their performance. Speakers and amplifiers alike are usually rated around 8 ohms, but that's not ...

A common joke in electronics is that every piece of wire and PCB trace is an antenna, with the only difference being whether this was intentional or not. In practical terms, low-frequency wiring is ...

We always enjoy a [FesZ] video and we wonder if the “Z” stands for impedance? That’s the topic of his latest video series: measuring impedance with LTSpice. Of course, he also does his usual thorough ...

Marelli is bringing one of the most powerful tools for lab-testing EV batteries—electrochemical impedance spectroscopy (EIS)—under the hood. Details on a BMS based on electrochemical impedance ...
