All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

Baluns enable impedance matching, minimize signal distortion, and suppress common-mode noise in RF and high-frequency designs ...

As you probably know if you've been shopping for cables, coax for most video applications is "75 ohm" coax–but what the heck does that mean, anyway? This article is a short, non-technical explanation ...

The explosive growth of electric vehicles, renewable energy integration, and large-scale energy storage systems has placed ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...

Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

Guest columnist Subhodeep Ghosh of Cypress Semiconductor looks into the stability issues affecting the usefulness of powerline communications as a networking technology. Powerline communications (PLC) ...

If you are an old hand at RF design, you probably have a good handle on matching impedance. However, if you are just getting started with RF, [FesZ Electronic]’s latest video series on lossless ...

The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...
