Sentence examples for variation of impedance from inspiring English sources

The variation of impedance can be easily measured with a commercial LCR meter.

This results in a variation of impedance on the film coupled with the planar spiral coil as well as in the corresponding voltage output to be measured.

For this purpose, it is considered that the voltage is imposed and independent of mechanical aspect and that the mechanical defect appears only in the current thanks to the variation of impedance.

Diffusion can also be associated to local variations of impedance (e.g., a flat reflective surface that exhibits areas of acoustically absorbing material) [22].

The amount of mineral admixture becomes decisive for the variations of impedance spectra, model parameter and carbonation depth.

Although this estimate is equal to the observed temporal variations in impedance data (within one order of magnitude), both the polarity and the periods of time during which the peak variations of impedance occur (green curved lines in the 2nd and 4th plots from the top in Fig. 7) do not correlate well with the temperature monitoring curves (top in Fig. 7).
