Power Spectral Density Function of {X(t)}
,
, • The power spectral density (PSD) of the signal describes
the power present in the signal as a function of frequency,
per unit frequency.
• Psdf describes how the intensity of a time-varying signal is
distributed in the frequency domain.
• PSD of a signal gives an analysis of the distribution of
power over the entire frequency range. The main objective
of using this method is to obtain the spectral density
estimation from the given data. It is estimated by
calculating the Fourier transform (FT) of the signals’
autocorrelation function. It perceives the signal as a
stochastic process and then determines its power.
