Alphabetical list of terms

Record 1 2017-11-23

English

Subject field(s)
  • Measuring Instruments (Engineering)
  • Acoustics (Physics)
DEF

A tube used to measure the speed of sound ...

OBS

[It] is filled with air or other gas and contains a light powder which becomes lumped at nodes, giving the length of standing waves generated in the tube.

French

Domaine(s)
  • Instruments de mesure (Ingénierie)
  • Acoustique (Physique)
DEF

Tube employé pour mesurer la vitesse du son.

OBS

Le tube est rempli d'air ou d'un autre gaz et il contient une fine poudre qui va s'accumuler aux nœuds de déplacement, ce qui provoque l'apparition d'ondes stationnaires dans le tube.

Record 2 2017-06-27

English

Subject field(s)
  • Semiconductors (Electronics)
  • Electronic Components
  • Conductors and Resistors
DEF

A voltage-controlled semiconductor which has a high input impedance comparable to that of a vacuum tube.

CONT

Field effect transistors are used to replace vacuum tubes in equipment for improved reliability.

OBS

field-effect transistor; FET: term and abbreviation term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Semi-conducteurs (Électronique)
  • Composants électroniques
  • Conducteurs et résistances
DEF

Dispositif à semi-conducteurs commandé par la tension et présentant une impédance d'entrée très élevée, analogue à celle d'un tube à vide.

OBS

Remplace le tube à vide dans certains équipements étant donné sa performance et une sûreté de fonctionnement plus grande.

OBS

transistor à effet de champ : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Spanish

Campo(s) temático(s)
  • Semiconductores (Electrónica)
  • Componentes electrónicos
  • Conductores y resistencias
DEF

Dispositivo semiconductor, de tres terminales, que actúa como elemento de almacenamiento de carga variable.

Record 3 2011-10-12

English

Subject field(s)
  • Vacuum Tubes (Electronics)
DEF

A high-vacuum electron tube having a high input impedance(low control-electrode conductance) to facilitate measurement of extremely small direct currents or voltages.

OBS

electrometer tube: term officially approved by the Electronics and Telecommunications Terminology Committee.

French

Domaine(s)
  • Tubes et lampes (Électronique)
OBS

tube électromètre : terme uniformisé par le Comité d’uniformisation des termes de l’électronique et des télécommunications (CUTEL).

Spanish

Campo(s) temático(s)
  • Tubos de vacío (Electrónica)

Record 4 2004-02-04

English

Subject field(s)
  • Electrical Circuits and Circuit Breakers
  • Vacuum Tubes (Electronics)
DEF

The effect on the input impedance of a valve circuit of the internal capacitive coupling between the control grid and the anode of the tube.

French

Domaine(s)
  • Circuits électriques et coupe-circuits
  • Tubes et lampes (Électronique)
DEF

Effet du couplage capacitif interne entre l'anode d'un tube électronique et la grille de commande sur l'impédance d'entrée de la grille de commande.

Spanish

Campo(s) temático(s)
  • Circuitos eléctricos e interruptores automáticos
  • Tubos de vacío (Electrónica)
Save record 4

Record 5 2002-11-13

English

Subject field(s)
  • Amplifiers (Electronics)
CONT

We have to consider what type of gain device is suitable for this application. Actually the choice is simple : Bipolar devices have too low an input impedance to be useable, and tubes have too little gain to be used in a single stage power amplifier. The only usable device is the power Mosfet, which is a transconductance device like the tube, and has a high input impedance, but operates with enough gain at high enough currents to be driven directly by line-level signal.

French

Domaine(s)
  • Amplificateurs (Électronique)
