Record 3 2017-07-10

English

Subject field(s)
  • Electrical Circuits and Circuit Breakers
  • Electrical Engineering
DEF

A coupling that allows the passage of AC [alternative current] signals but blocks DC [direct current] signals.

OBS

In analog circuits, [this] technique helps to isolate the DC bias settings of the two coupled circuits.... the capacitor used for the purpose is also known as a DC-blocking capacitor.

OBS

AC or capacitive coupling is achieved by placing a capacitor in series with the signal to be coupled.

OBS

ac coupling: term officially approved by the Lexicon Project Committee (New Brunswick).

Key term(s)
  • A.C. coupling

French

Domaine(s)
  • Circuits électriques et coupe-circuits
  • Électrotechnique
DEF

Transmission d'énergie électrique par un condensateur proprement dit ou entre deux conducteurs formant condensateur, et notamment transmission d'un signal parasite entre deux circuits par une capacité parasite.

OBS

couplage AC : L'abréviation «AC» vient de l'anglais «alternating current».

OBS

couplage c.a. : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Key term(s)
  • couplage A.C.

Record 4 2005-04-08

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
DEF

Objective forecast based on a statistical examination of the past behaviour of the atmosphere, using regression formulae, probabilities, etc.

CONT

Statistical predictions [are] predictions based mainly on large observational data sets. CCA [Canonical correlation analysis], OCN [Optimal Climate Normals], SMLR [Screening Multiple Linear Regression], CAS [Constructed Analog Soil Moisture Prediction Technique], CA [Constructed Analog] are examples of these.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
DEF

Prévision objective basée sur l'étude statistique du comportement passé de l'atmosphère et utilisant des équations de régression, des probabilités, etc.

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
DEF

Predicción objetiva basada en el examen estadístico del comportamiento pasado de la atmósfera, expresado bajo la forma de ecuaciones de regresión, de probabilidades, etc.

Record 5 2004-05-10

English

Subject field(s)
  • Scientific Research Methods
  • Information Processing (Informatics)
DEF

A process for the transmission, processing and storage of information in which the signal can be assigned any value in a specific area - in contrast to digital technique.

CONT

A common feature of all configurations discussed above is the production of large data volumes. A conventional photogrammetric photo stores a volume totalling about 8 Gbits(b/w) on film by an analog technique.

French

Domaine(s)
  • Méthodes de recherche scientifique
  • Traitement de l'information (Informatique)
DEF

Processus de transmission, de traitement et de stockage d'information dans lequel n'importe quelle valeur d'une zone précise est assignée au signal.

CONT

La technique analogique existe depuis un certain temps et son principal atout réside dans la simplicité d'installation du récepteur.

Record 6 2003-02-06

English

Subject field(s)
  • Operating Systems (Software)
  • Computer Memories
CONT

FISO technology uses a patented technique of performing analog sampling using standard semiconductor technology. Samples are stored as electric charge in each of the 10, 000 on-chip cells.... Once the analog sampling has finished, a slow speed, very accurate 9-bit A/D converter is used to convert the stored analog values into digital code.

Record 8 1987-01-07

English

Subject field(s)
  • Information Processing (Informatics)
CONT

In the field of ADC(analog-to-digital conversion), two main techniques are used : the successive-approximation technique, and the dual-slope integration. In the successive-approximation technique, an analog input value is compared to the analog value of a counter and progressively, a finer approximation is generated.

French

Domaine(s)
  • Traitement de l'information (Informatique)
DEF

Technique qui consiste à comparer une valeur d'entrée analogique à celle d'un compteur (convertie en analogique) et à engendrer progressivement une approximation de plus en plus fine.

Record 9 1981-04-21

English

Subject field(s)
  • Genetics
DEF

Technique using Bromodeoxyuridine(BUdR) which is a thymidine analog that can be incorporated into the DNA of replicating cells growing in a medium where such a compound is present. BUdR added to the culture medium in the last hours before harvesting is incorporated into late replicating DNA and induces a condensation delay in late replicating DNA segments, allowing the identification of late replicating chromosomes without the need of autoradiography.

CONT

The BUdR technique has already found successful application in clinical cytogenetics; identification and delineation of inactive X chromosomes in cases of balanced and unbalanced X-autosomal translocation have been recently achieved (1975). The demonstration of sister chromatid exchanges in cases of Bloom syndrome, Fanconi’s anemia, and ataxia-telangiectasia has been made possible by this technique (1975).

French

Domaine(s)
  • Génétique
DEF

Technique utilisant de la bromodéxyuridine (BrdU) qui est un analogue de la thymidine qui peut être incorporé à l'ADN des cellules en réplication se développant dans un milieu où se trouve ce composé. La BrdU additionnée au milieu de culture dans les dernières heures avant la récolte, est incorporée à l'ADN qui se réplique tardivement, et entraîne un retard de condensation au niveau des segments d'ADN se répliquant tardivement; ceci permet l'identification des chromosomes se dupliquant tardivement sans utiliser l'autoradiographie.

CONT

(Syndr. de Turner) Les techniques permettant d'étudier la réplication de l'X (autoradiographie ou mieux BrdU)montrent que dans la très grande majorité des cas c'est l'X remanié qui est «inactivé».
