Wavelet Analysis – Building on the foundations of signal analysis in electrical engineering Pahk and Klinzing (2008) tried to analyze the signal of the pressure fluctuation in order to what actually made up these fluctuations and could can we indeed read this signal in a more intelligent manner. Detailed analysis using the wavelet approach indicates that the
various contributions of the pressure fluctuations can be filtered out of the signal to provide a more detailed analysis of the system. Figure 6 is one result of this analysis which distinctly picks out the blower, feeder, turbulence and solids interactions terms.
