Power-law Noise
Many of these definitions assume a signal with components at all frequencies, with a power spectral density per unit of bandwidth proportional to 1/f β and hence they are examples of power-law noise. For instance, the spectral density of white noise is flat (β = 0), while flicker or pink noise has β = 1, and brown noise has β = 2.

Famous quotes containing the word noise:
“Speak, ye that ride on white asses, ye that sit in judgment, and walk by the way.
They that are delivered from the noise of archers in the places of
drawing water, there shall they rehearse the righteous acts of the
Lord,”
