The main goal of this paper is to characterize the low-frequency part of ADC transfer function by dual tone testing from intermodulation components that are independent of test signal harmonic distortion. The theoretical analyses of incoherently sampled signals in the frequency domain and of intermodulation distortion are provided and the theory is verified by experimental results.

The interaction between ultrasonic waves and biological tissues is the cause of cavitation phenomena. A primary scope of this paper was to set-up a measurement system for the generation of cavitation by means of forcing a low frequency (20 kHz). From the spectra and power density was evident the presence of the random component associated to the noise of cavitation was evident. For the estimate...

Vacuum technology is one of the established advanced technologies, of present age, in the field of research and industry. Having numerous applications, in the areas of human activities, one is concerned with a relatively large vacuum chamber where pressure distribution is, usually, not uniform during dynamic gas flow. To minimize the pressure non-uniformities in such chambers, baffles are gener...

− The Laboratory of Biometrology of PUCRio has been developing magnetic field transducers to be used in biomedical applications. Investigations recently accomplished indicate the possibility of a new research line, which considers the changes in the phase characteristics of Giant Magnetoimpedance (GMI) sensors due to varying low-intensity magnetic fields. In spite of being less explored in the ...

− An automatic test system for clinical electrical thermometers was developed to enhance the efficiency of error tests. Besides the temperature measurement unit, mechanical drive and machine vision units were designed to implement automatic tests. An uncertainty analysis was also presented. According to the special measurement action of clinical thermometers, the Monte Carlo method was used to ...
