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:
“With the noise of the mourning of the Swattish nation!
Fallen is at length
Its tower of strength;
Its sun is dimmed ere it had nooned;
Dead lies the great Ahkoond,
The great Ahkoond of Swat
Is not!”
—George Thomas Lanigan (1845–1886)
