**(PDF) SIGNAL PROCESSING FOR POWER SPECTRAL DENSITY (PSD)**

Power Spectral Density (PSD) is a measure of a signal's power intensity in the frequency domain.In practice, the PSD is computed from the FFT spectrum of a signal.... Since the power spectral density is the Fourier transform of the autocorrelation function, the PSD of white noise is a constant. Therefore, all frequency components are equally present--hence the name ``white'' in analogy with white light (which consists of all colors in equal amounts).

Moses, "Spectral analysis of signals ", available on-line at... The velocity components of the atmospheric wind typically have a power spectral density (PSD) with a slope of –5/3 in an “inertial subrange” of frequencies, roughly from 0.01 to >10 Hz depending on the wind speed and stability.
