Understanding Power Spectral Density and the Power Spectrum
And so to get power spectral density, we divide the power spectrum by the equivalent noise bandwidth. We know power spectrum is the absolute value of the FFT squared divided by N^2. And this is the equation for the equivalent noise bandwidth for an …
Operational Modal Parameter Identification from Power Spectrum Density ...
In this article, the power spectrum density transmissibility (PSDT) is proposed to extract the operational modal parameters of a structure. It is proven that the PSDT is independent of the applied excitations and transferring outputs at the system poles. As a result, the modal frequencies and mode shapes can be extracted by combing the …
