Record 1 2015-04-08

English

Subject field(s)
  • Mathematics
  • Computer Graphics
  • Acoustics (Physics)
CONT

A more complicated kind of scaling noise is one that is sometimes called Brownian noise because it is characteristic of Brownian motion, the random movements of small particles suspended in a liquid and buffeted by the thermal agitation of molecules.

French

Domaine(s)
  • Mathématiques
  • Infographie
  • Acoustique (Physique)
DEF

Type de bruit scalant caractérisé par le mouvement brownien.

CONT

Un type plus compliqué de bruit scalant est ce que l'on appelle quelquefois le bruit brownien, parce qu'il est caractérisé par le mouvement brownien, mouvement aléatoire de petites particules en suspension dans un liquide et soumises aux chocs des molécules en agitation thermique.

Record 3 2012-06-04

English

Subject field(s)
  • Television (Radioelectricity)
  • Radar, Radio Guidance and Goniometry
DEF

Small, random, white spots produced on a television or radar screen by inherent noise signals originating in the receiver.

CONT

... noise has its most deleterious effect on reception quality when it occurs in the input circuitry of the receiver, since this is usually where the basic signal-to-noise ratio is established. The generation of noise in this area is principally caused by thermal agitation in resistive input components. When the incoming signal is too weak to override this noise, a visual effect is displayed on the picture tube that is commonly referred to as snow. Although there are other types of noise that produce different visual effects, snow is the most common visual effect.

French

Domaine(s)
  • Télévision (Radioélectricité)

OBS

Ce terme sert à désigner une image très fortement dégradée par le bruit.

English

Subject field(s)
  • Music (General)
CONT

When tones fluctuate in this fashion, let us follow Voss and call it Brownian music or brown music.

OBS

(...) Brownian noise(...) is characteristic of Brownian motion, the random movement of small particles suspended in a liquid and buffeted by the thermal agitation of molecules.
