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 ...

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 ...

The AD5933/4 impedance-to-digital converters allow an external complex impedance (range 100 W to 10 MW) to be excited with a known frequency of up to approximately 100 kHz. The response signal from ...

Researchers have demonstrated an improved version of impedance cytometry that uses four frequencies of applied AC voltage to measure the size and shape of individual microorganisms. By ensuring that ...

The question of time vs. frequency, as the most useful measurement domain, has long been a controversial topic. In some cases, it leads to rather heated discussions. The argument in favor of a vector ...
