The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing Fisheries and Oceans Canada's (DFO) capacity to understand, describe, and forecast the state of the marine ecosystem and quantifying the changes in the ocean's physical, chemical, and biological properties and the predator–prey relationships of marine resources. 2, record 1, English, - Atlantic%20Zone%20Monitoring%20Program

The [Atlantic Zone Monitoring Program] sampling strategy is based on: seasonal and opportunistic sampling along sections to quantify the oceanographic variability in the Canadian Northwest Atlantic [continental] shelf region; higher frequency temporal sampling at more accessible stations to monitor the shorter time scale dynamics in representative areas. 3, record 1, English, - Atlantic%20Zone%20Monitoring%20Program

Conçu pour satisfaire les amoureux de musique et les audiophiles les plus sagaces, le nouveau format DVD audio offre ce qu'il y a de mieux en matière de qualité audio. Il garantit une fréquence d’échantillonnage très élevée de 192 kHz(celle d’un CD n’ est que de 44, 1 kHz) et une résolution de 24 bits(16 bits pour un CD). La résolution audio est environ 1 000 fois supérieure à celle du format CD, avec une plage de fréquences supérieure à 96 kHz(20 kHz pour un CD) et une gamme dynamique s’étendant à 144 dB(celle d’un CD est d’environ 96 dB). 3, record 14, French, - r%C3%A9solution%20audio

Super Audio CD (SACD) is a technology for high resolution multi-channel digital audio recordings proposed by Sony and Philips. SACD albums must contain one layer with the "Direct Stream Digital" encoding format which requires a SACD capable player. "Direct Stream Digital" encoding will be able to provide a frequency response from DC to 100 kHz with a dynamic range of 120 dB. Multichannel SACD players have 6 outputs and can play 5.1 or 6 channel audio. SACD albums can optionally contain a second layer encoded with the CD-format (PCM at 44.1-kHz/16-bit) in stereo allowing compatibility with existing CD players. 1, record 18, English, - Direct%20Stream%20Digital%20encoding

Un signal étant rarement pur, des harmoniques(Fh) ou des signaux parasites vont se combiner avec la fréquence d’échantillonnage pour donner naissance à des fréquences d’intermodulation [...] Pour éliminer ces fréquences perturbatrices dans la bande utile, il y a lieu de mettre un filtre passe-bas que l'on nomme filtre «antialiasing» ou «antirepliements». 1, record 26, French, - antirepliement

An ambiguity in the frequency represented by sampled seismic data. Where there are fewer than two samples per cycle, an input signal at one frequency yields the same sample values as, and hence appears to be, another frequency at the output of the system. Half of the frequency of sampling is called the "folding" or "Nyguist" frequency, fN;a frequency larger than this, fN+Y, appears to be the smaller frequency, fN-Y. The two frequencies are "aliases" of each other. 2, record 27, English, - alias

L'échantillonnage du signal provoque une ambiguïté sur les fréquences, à cause des phénomènes de repliement du spectre. [...] On peut montrer qu'il n’ y a pas de phénomène de repliement si l'on s’arrange pour ne pas avoir de signal à des fréquences supérieures à la fréquence de Nyquist(moitié de la fréquence d’échantillonnage). 4, record 27, French, - fr%C3%A9quence%20repli%C3%A9e

Lower master clock frequency: While our D/A converter uses a high-speed 384-times oversampling frequency, it runs at a relatively low clock frequency of 16.9344 MHz. This minimizes the effect of jitter on sound quality and ensures better, clearer sound. 1, record 28, English, - lower%20master%20clock%20frequency

Le codage de base pour le son numérique est PCM(«Pulse Code Modulation»), que l'on traduit assez rarement par MIC(Modulation par Impulsions Codées). Ce codage est une simple transformation des signaux analogiques en signaux numériques. Il n’ inclut aucune compression sonore. C'est le type de codage utilisé par le CD-audio et les cartes sonores pour micro-ordinateurs. Les deux paramètres significatifs de ce codage sont la fréquence d’échantillonnage(en kHz) et la quantification(en bits). Le Tableau 5. 4 montre les domaines d’application selon l'échantillonnage et la quantification. 1, record 29, French, - codage%20PCM

A filter used before sampling to remove undesired frequencies which the sampling process would otherwise alias. An alias filter should have linear phase response and nearly flat amplitude response over the signal passband and should roll off rapidly above this band to provide high attenuation above the Nyquist frequency (.,..)

Afin d’éviter ces phénomènes, il est donc nécessaire de filtrer l'enregistrement avant l'échantillonnage afin de l'épurer de toutes les fréquences supérieures à la fréquence de Nyquist. On utilise à cet effet un filtre à pente raide, dit filtre antialiasing, dont la fréquence est naturellement adaptée à l'échantillonnage. 1, record 32, French, - filtre%20antialiasing
