Alphabetical list of terms

Record 1 2016-07-11

English

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

A receiver in which all incoming modulated RF [radiofrequency] carrier signals are converted to a common intermediate frequency carrier value for additional amplification and selectivity prior to demodulation, using heterodyne action.

Key term(s)
  • super-heterodyne receiver

French

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

Appareil qui, par battement avec un générateur local, transforme une haute fréquence en fréquence plus basse.

OBS

Le changement de fréquence peut s'effectuer deux et même trois fois.

Key term(s)
  • récepteur super-hétérodyne
  • super-hétérodyne

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
  • Guía radárica, radioguía y radiogoniometría
DEF

Receptor en el que las señales de radiofrecuencia entrantes, normalmente se amplifican en un preamplificador y entonces se alimentan en un mezclador para la conversión de una frecuencia portadora fija y más baja (llamada frecuencia intermedia).

Record 2 2014-01-09

English

Subject field(s)
  • Radio Transmission and Reception
  • Telecommunications Facilities
CONT

Demodulation of [a] signal requires a system that produces an output proportional to the instantaneous frequency deviation of the input signal. Such a system is called a frequency discriminator.

French

Domaine(s)
  • Émission et réception radio
  • Installations de télécommunications

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
  • Instalaciones de telecomunicaciones

Record 3 2011-10-27

English

Subject field(s)
  • Radio Broadcasting
  • Telecommunications Transmission
DEF

A form of amplitude-modulation in which a carrier is transmitted at a controlled level below that which is required for demodulation, but at a level sufficient to serve as a frequency reference.

OBS

reduced-carrier transmission: term officially approved by the Electronics and Telecommunications Terminology Committee.

Key term(s)
  • reduced carrier transmission

French

Domaine(s)
  • Radiodiffusion
  • Transmission (Télécommunications)
OBS

émission à porteuse réduite : terme uniformisé par le Comité d’uniformisation des termes de l’électronique et des télécommunications (CUTEL).

Spanish

Campo(s) temático(s)
  • Radiodifusión
  • Transmisión (Telecomunicaciones)

English

Subject field(s)
  • Radio Broadcasting
  • Telecommunications
DEF

The demodulation applicable to a modulated signal produced by frequency modulation.

French

Domaine(s)
  • Radiodiffusion
  • Télécommunications
CONT

L'intérêt spectral de ces modulations est accru par la possibilité d'utiliser une technique de démodulation très simple : la démodulation de fréquence.

Spanish

Campo(s) temático(s)
  • Radiodifusión
  • Telecomunicaciones
DEF

Demodulación aplicable a la señal modulada producida por modulación de frecuencia.

Spanish

Campo(s) temático(s)
  • Transmisión (Telecomunicaciones)
  • Radiotransmisión y radiorrecepción
  • Estaciones terrenas
DEF

Dispositivo que forma parte del equipo de la estación terrena y que realiza la desmodulación y la transposición de frecuencia.

Record 6 1998-08-18

English

Subject field(s)
  • Radio Waves

Record 7 1997-04-09

English

Subject field(s)
  • Electrochemistry
DEF

A component of the current that is due to the demodulation associated with an electrode reaction and that appears if an indicator or working electrode is subjected to the action of two intermodulated applied potentials of different frequency.

French

Domaine(s)
  • Électrochimie
DEF

C'est une composante du courant qui résulte de la démodulation associée à une réaction à l'électrode et qui apparaît lorsqu'une électrode indicatrice ou de travail est soumise à l'action de deux potentiels appliqués intermodulés, de fréquences différentes.
