Record 4 2002-05-13

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Telecommunications Transmission
DEF

The ratio to the unit interval of the maximum measured difference, irrespective of sign, between the actual and theoretical intervals separating any significant instant of modulation (or of restitution) from the significant instant of the start element immediately preceding it.

OBS

Degree of distortion of a start-stop modulation(or restitution) is usually expressed as a percentage.

French

Domaine(s)
  • Mesures et analyse (Sciences)
  • Transmission (Télécommunications)
DEF

Rapport à l'intervalle unitaire du maximum des différences mesurées, prises en valeur absolue, entre les intervalles réels séparant tout instant significatif de la modulation (ou de la restitution) de l'instant significatif de départ qui le précède immédiatement, et les intervalles théoriques correspondants.

Spanish

Campo(s) temático(s)
  • Medición y análisis (Ciencias)
  • Transmisión (Telecomunicaciones)
DEF

Razón, con respecto al intervalo unitario, de la diferencia máxima medida, tomada en valor absoluto, entre el intervalo teórico que separa un instante significativo cualquiera de la modulación (o de la restitución), del instante significativo del elemento de arranque que le precede inmediatamente.

OBS

El grado de distorsión de una modulación (o restitución) arrítmica se expresa generalmente en tanto por ciento.

English

Subject field(s)
  • Internet and Telematics
  • Electronics
DEF

In a modulation system, the smallest value of carrier-to-noise ratio at the input to the demodulator for all values above which a small percentage change in the input carrier-to-noise ratio produces a substantially equal or smaller percentage change in the output signal-to-noise ratio.

French

Domaine(s)
  • Internet et télématique

DEF

Niveau à ne pas dépasser (en plus ou en moins). Exemple : Seuil d'une impulsion : valeur minimum en dessous de laquelle l'impulsion perd sa signification et risque d'être confondue avec un parasite.

Spanish

Campo(s) temático(s)
  • Internet y telemática
  • Electrónica
DEF

Record 6 1989-08-02

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Radio Transmission and Reception
OBS

Angle errors due to the modulation of the signal by the target are a function not only of the frequency and percentage of modulation, but also of the beam width of the radar itself.

OBS

The direction of the target is determined by measuring the angle at which the returning wavefront arrives at the radar. The common method for accomplishing this measurement is with a directive antenna, i.e., one with a narrow radiation pattern.

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Émission et réception radio
OBS

Calcul de l'erreur de position de la cible que donne l'écho à l'aide de l'angle d'arrivée du front de signal.

  • Air Navigation Aids
OBS

for the conventional VOR, the percentage of amplitude modulation of the 9960 Hz subcarrier shall not exceed 5 per cent.

French

Domaine(s)
  • Aides à la navigation aérienne
OBS

dans le cas du VOR classique, le taux de modulation en amplitude de la sous-porteuse de 9960 Hz ne dépassera pas 5 pour cent.
