  • Measurement of three independent components in impedance sensors using a single square wave 

    Lario García, Javier; Pallàs Areny, Ramon (Elsevier, 2003-12-17)
    Article
    Open Access
    Two-wire impedance-based sensors involving electrolytes add the impedance of the electrodes to the electrical impedance of the medium to measure. An equivalent circuit for the measured impedance is a resistance in series ...
  • Subsurface resistivity measurements using square waveforms 

    Gasulla Forner, Manuel; Jordana Barnils, José; Pallàs Areny, Ramon; Torrents Dolz, Josep M. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-02-28)
