Record 2 2021-09-23

English

Subject field(s)
  • Electronics
DEF

[A] field of electronics involving the study of digital signals and the engineering of devices that use or produce them ...

CONT

In digital electronics, the electrical signals produced by sensors are converted into numeric form; this is called analogue-to-digital conversion. Once the sensor's information is in a digital format, the signal can be analysed mathematically using specifically written software.

French

Domaine(s)
  • Électronique
CONT

L'électronique numérique est un domaine scientifique s'intéressant aux systèmes électroniques dont les états parcourent un ensemble fini de possibilités. Le déterminisme dans les changements d'état (transitions) permet de disposer de systèmes qui se comportent de manière stable et fiable. Elle permet en particulier de s'affranchir de parasites et autre déformations.

Record 4 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.

English

Subject field(s)
  • Measuring Instruments
  • Scientific Instruments
DEF

[A recording device that] converts the electrical signal generated by any measurement, such as the beating of the heart or respiration rate, into a written record using an ink pen and a moving strip of paper.

French

Domaine(s)
  • Appareils de mesure
  • Instruments scientifiques
DEF

Appareil enregistreur qui transforme le signal électrique induit par une mesure, telle que celle du rythme cardiaque ou de la fréquence respiratoire, afin de l'inscrire sur un diagramme grâce à un stylet et une bande déroulante de papier.

Record 6 2005-01-25

English

Subject field(s)
  • Television (Radioelectricity)
  • Computer Graphics
  • Applications of Automation
  • Video Technology
DEF

A standard of quality for the reproduction of video signals.

CONT

There is a further version of the CD-I known as full-motion video (FMV). In this format, audio and video are encoded using the MPEG standard ... This means that full-motion video with high-quality stereo can be output from a CD.

CONT

Although real motion video is the holy grail of multimedia, it still is impractical using today's technology. The current method for working with video is by capturing and converting the analog signal from a video source and either manipulating the image's data(which is written to video tape) or compressing the data using compression techniques(either software-only compression or a combination of hardware and software compression). To display or capture a single screen of an NTSC [National Television System Committee] signal, you must have a video frame grabber.... Real-time frame grabbers capture full-motion video at a rate between 15 and 30 frames-per-second using video compression...

OBS

In the NTSC format, it is achieved when the video signal is reproduced at 30 frames per second and in the PAL format, it occurs at 25 fps.

OBS

CONT

Le CD-I fait appel à des techniques très sophistiquées de compression d'images pour pouvoir stocker des images animées, très consommatrices d'espace. L'algorithme de compression est baptisé «Full Motion Video» (FMV). C'est la mise au point de cet algorithme qui a permis au CD-I de pouvoir afficher jusqu'à 72 minutes d'images animées plein écran. La qualité de l'image ainsi traitée est équivalente à celle d'un magnétoscope VHS mais inférieure à celle d'un LaserDisc.

Grâce à une carte d'acquisition vidéo, il devient possible de capturer des séquences issues d'un magnétoscope ou d'un caméscope [...] Les cartes d'acquisition ont pour fonction de numériser les images analogiques. Cette numérisation doit se faire en temps réel. L'objectif est donc d'acquérir, de numériser, de compresser et de stocker sur disque 25 images à la seconde. Bien sûr, toutes les cartes n'offrent pas ces performances.

These are lowest on the rungs of the video ladder, in that they have less capability than boards that capture streaming video. These cards enable you to grab a single frame of video from a Laser Disk or a VCR. Video frame grabbers come in two varieties : single-frame capture and real-time capture. Single-frame capture boards enable you to freeze a selected frame and record it to your hard disk. In this function, single-frame boards are similar to scanners-they provide a means of capturing an image and saving it for use in a multimedia title.
