| Abstract: | In order to detect the instantaneous amplitude from instantaneous frequency separately, this paper studies the Hilbert transform demodulation approach and Teager energy operator demodulation approach for modulated signal and puts forward detailed algorithm and application precautions. Simulated signal is used to carry out contradistinctive analysis to the approaches. The result indicates that the later approach has preferable effect and can be widely used in the analysis of mechanic vibration signal demodulation. |
