— This paper analyzes the advantages and limitations of using the floating-(or flying-) capacitor technique as a building block with differential input and either differential or single-ended output to implement voltage amplifiers, multiplex-ers, and coherent amplitude demodulators. Theoretical analysis, supported by experimental results, shows that the(More)
— This work analyzes the effect of inductive and capacitive coupling between the injecting circuit and the detecting circuit in resistive field surveys. Theoretical and experimental results demonstrate that if a square waveform is injected into the soil, and synchronous sampling is used to sample at the flat zone of the detected voltage, then the effect of(More)
− Conventional concrete structures are nowadays being substituted by steel fibre reinforced concrete (SFRC) in some structural applications. Then, fibre dosage and distribution is a keyword for ensuring quality control of structures. The present work analyses the possibility of an Open Ended Coaxial Probe as an element for ensuring the quality of a concrete(More)
