To assess the variation in whole-body and segmental bioelectrical impedance measured in the standing position over the course of a day. Sixteen healthy men aged 29.6±3.1 years participated in this ...

Measuring the output impedance of wideband op amps presents a formidable challenge because of their high DC gain, which results in low closed-loop output impedance at low frequencies. Above the ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

Here are some tips and information on making impedance measurements on power distribution systems. As you probe around at different locations on the plane you will find that the higher frequency ...

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 ...

BMW has patented a calibration method for an electrochemical impedance measuring device used to measure an electrochemical cell’s impedance. The method involves connecting the device to an impedance ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

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 ...
