No programming skill is required. User can build the data analysis diagram with several simple mouse clicks and the results are ready for viewing and final reporting. Besides HHT algorithm, DataDemon includes tools for data filtering, math calculation, statistics, matrix operation, data transformation and other popular time- frequency analysis (TFA) methods, such as short-term Fourier transform, (Enhanced) Morlet wavelet, and Hilbert transform etc. DataDemon software is available now in both Academic and Professional versions.
