The accuracy or error of a phase difference measurement between two different si nusoidal signals is significantly affected by the noise in them. Quadrature Demodulation (QD) is one of the methods used for calculating the ...

Many known literature techniques are available to detect flicker in electric power systems and to mitigate them. However, they are not suitable to detect random flicker in the presence of the higher-order harmonics. This ...

For accurate analysis and characterization of materials using Raman spectroscopy, it is often necessary to remove signal distortions, including the noise from the spectra, using a filter such as the Savitzky-Golay (SG) ...
