抄録

In our laboratory, a polymer piezoelectric vibrator and an acoustic emission sensor have been used for generation of pressure waves in dielectric liquids. A large amount of noise is contained in experimental data of charge distribution obtained using the pressure wave method. For removal of this noise, the wavelet transform was used in the data analysis. The noise removal from and time-frequency analysis of experimental data were performed simultaneously. The removal of noise from data using the wavelet transform could make more clear waveform than waveform of measured data. Therefore, it was clear that the wavelet analysis can be applied to measurement of charge distribution in dielectric liquids using the pressure wave method.
