| Abstract: | The instantaneous power spectrum of nonstationary random vibration signals is discussed in this paper.First of all,the advantages and short comings of existing instantaneous power spectrums are reviewed.Then a new kind of instantaneous power spectrum is advanced and its main properties are proved.Finally an example is quoted to compare the new instantaneous power spectrum with the existing one. |
