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 ...

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 ...

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 ...

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 ...

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, ...

Two new ICs are described as fully integrated devices that offer direct capacitance-to-digital and impedance-to-digital conversion. The single-chip AD7745 integrates all stages of ...

Patient monitors measure and display the various vital signs of the connected patient. The main signature of interest is the patient’s electrocardiogram (ECG) signal, but other parameters of interest ...

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 ...
