(n) and η(n) are the modulated and noise signal, respectively, then the cyclic spectral density function of y(n) is (Gardner, 1991) Syyfα=∑τryyατe−j2πfτ, where ryyατ=Eyn+τy∗n−τej2παn is the cyclic autocorrelation function, and α is the cyclic frequency...
The spectrum length is NFFT and is computed over [0,2π) if Fs is not specified or [0,Fs) if Fs is specified. Entering 'onesided' returns the one-sided PSD, which contains the total signal power. Hmss = psd(Hs,X,'NormalizedFrequency',true) returns a power spectral density object ...

3.1 Spectral derivatives (Norris-William derivatives and Savitzky-Golay filtering) Spectral derivatives function to eliminate constant and linear baseline drift and resolve the peak overlap in the spectra [47]. The first and second derivatives are commonly used compared to higher-order derivatives to ma...
Spectral density curves are determined for given Ms. Comparison of the theoretical curves with observations is made in two different ways. The observed ratios of the spectra of seismic waves with the same propagation path but from earthquakes of different sizes are compared with the corresponding ...
