Abstract: The principle of the energy operator demodulation approach is summarized. The comparison of this method with the Blbert transform demodulation approach is made. The application in the mechanical signals demodulation is studied. The results show that the energy operator demodulation approach is a very good demodulation method, and it will play an important role in the analysis of mechanical signals.

Key words: Demodulation, Energy operator, Mechanical signal
