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:
“I’ve almost gained my heav’nly home; My spirit loudly sings;
The holy ones behold they come, I hear the noise of wings.
O come, angel band, Come and around me stand.
O bear me away on your snowy wings, To my immortal home.”
—T. Haskell, minister and hymn-writer. Published in Christian Harmony. “Angel Band,” l. 5-8.
