Unwanted or unintentional interference in a signal

Subcategories

  • 1f noise - also known as pink noise, a signal with a frequency spectrum such that the power spectral density is inversely proportional to the frequency
  • Additive noise - white noise added to a given signal
  • Colored noise - random noise that has certain characteristic statistical properties corresponding to different mappings from a source of randomness
  • Gaussian noise - statistical noise that has its probability density function equal to that of the normal or Gaussian distribution
  • Laser noise - fluctuations of various parameters of laser output
  • Noise cancellation or active noise control, the use of a speaker with the same amplitude but an inverted phase to an original sound
  • Phase noise - noise of the optical phase of a beam or electric signal
  • Signal to noise ratio - a measure of the level of a desired signal relative to the level of background noise
  • Superconducting device noise - devices using superconductiing material that transmit very low noise levels
