Record 3 2006-01-11

English

Subject field(s)
  • Telephone Metering
  • Telecommunications Transmission
  • Remote Sensing
DEF

In analog and digital communications, signal-to-noise ratio, often written S/N or SNR, is a measure of signal strength relative to background noise[;] the ratio is usually measured in decibels (dB).

OBS

This ratio is usually in terms of peak values in the case of impulse noise and in terms of the root-mean-square values in the case of random noise.

OBS

This ratio may be a function of bandwidth of the transmission system.

OBS

signal to noise ratio; SNR: term and abbreviation officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Téléphonométrie
  • Transmission (Télécommunications)
  • Télédétection
DEF

Pour un équipement électronique, ce rapport s'obtient en comparant le signal d'entrée avec le signal de sortie pour mesurer le niveau du bruit (signal parasite) ajouté par l'équipement.

OBS

Ce rapport s'exprime souvent en décibels (dB) ou parfois en népers (Np).

OBS

rapport signal sur bruit; rapport signal/bruit; SNR; S/B : termes et abréviations uniformisés par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Key term(s)
  • rapport signal bruit

Spanish

Campo(s) temático(s)
  • Telefonometría
  • Transmisión (Telecomunicaciones)
  • Teledetección
DEF

Relación entre las amplitudes de la señal deseada y del ruido en el mismo punto.

OBS

Normalmente se expresa en decibelios y da idea de la sensibilidad de un receptor de radio.
