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 ...

Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...

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 ...

Keysight Technologies, Inc. announced shipment of its E4991B impedance analyzer, specifically designed for R&D, quality assurance and inspection engineers characterizing and evaluating passive ...

Bioelectrical impedance analysis is a noninvasive and rapid method for estimating body composition, including body fat and muscle mass. Previous studies have indicated that bioelectrical impedance can ...

When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...

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, ...

had a question. If i have a 2-voice coil subwoofer and each voice coil is 2 ohms, then when I test either of the voice coils shouldn't I get 2 ohms or pretty close? I know where to put the multimeter ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...
