Audio and audiovisual equipment - Digital audio parts - Basic measurement methods of audio characteristics - Part 1: General

IEC 61606-1:2009(E) is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all of consumer use, professional use and personal computer. The common measuring conditions and methods, described in this standard, are used for the measurement of the performance characteristics of equipment having an audio bandwidth equal to approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are examples. It describes test methods for equipment which has digital input with analogue output and analogue input with digital output. Future revisions of this standard will cover digital-in/digital-out and analogue-in/analogue-out tests. It constitutes a technical revision. The significant technical changes with respect to the first edition are the following: - changed the period of preconditioning; - add A weighting filter in measuring instruments; - correct the wrong reference number; - some inappropriate descriptions have been improved.

Audio- und audiovisuelle Geräte - Digitale Tonteile - Grundlegende Messverfahren der Audio-Eigenschaften - Teil 1: Allgemeines

Equipements audio et audiovisuels - Parties audionumériques - Méthodes fondamentales pour la mesure des caractéristiques audio - Partie 1: Généralités

L'IEC 61606-1:2009 est applicable aux méthodes fondamentales pour la mesure des caractéristiques audio de la partie audionumérique des équipements audio et audiovisuels destinés à tous les usages grand public, professionnel et pour ordinateur individuel. Les conditions et les méthodes de mesure communes, décrites par la présente Norme, sont utilisées pour la mesure des caractéristiques de performance des équipements ayant une largeur de bande audio approximativement égale à la moitié de la fréquence d'échantillonnage du système dans lequel les informations audio sont traitées sous forme de données numériques. Les lecteurs de CD, les enregistreurs DAT, les amplificateurs numériques, les récepteurs de radiodiffusion numérique et les récepteurs d'émissions de télévision avec son numérique en sont des exemples. La présente Norme décrit des méthodes d'essai relatives aux équipements dont l'entrée est numérique et dont la sortie est analogique et celles relatives aux équipements dont l'entrée est analogique et dont la sortie est numérique. Les futures révisions de la présente Norme couvriront des méthodes d'essai relatives aux équipements dont l'entrée est numérique, ainsi que la sortie et celles relatives aux équipements dont l'entrée est analogique, ainsi que la sortie. La présente Norme ne s'applique pas à un signal de compression avec perte, ni aux amplificateurs de puissance. L'IEC 61606-1:2009 annule et remplace la première édition parue en 2003. Elle constitue une révision technique. Les modifications techniques majeures par rapport à la première édition sont les suivantes: - modification de la période de préconditionnement; - adjonction d'un filtre de pondération A dans les appareils de mesure; - correction du numéro de référence erroné; - certaines descriptions inadaptées ont été améliorées.

Avdio in avdiovizualna oprema - Digitalni avdio deli - Osnovne merilne metode zvokovnih karakteristik - 1. del: Splošno (IEC 61606-1:2009)

Ta del IEC 61606 velja za osnovne metode merjenja zvokovnih karateristik digitalnega avdia dela za avdio in avdiovizualne opreme za vso potrošniško uporabo, profesionalno uporabo in osebni računalnik. Splošni merilni pogoji in metode, opisani v tem standardu, se uporabljajo za merjenje karateristik delovanja opreme, ki ima pasovno širino avdia enako približno polovični pogostosti vzorčenja sistema, kjer je avdio informacija predelana v obliko digitalnih podatkov. Taki primeri so CD predvajalniki, DAT snemalniki, digitalni ojačevalci, digitalni zvočni sprejemniki in televizijski sprejemniki z digitalnim zvokom. Ta standard opisuje preskusno metodo za opremo ki ima digitalni vhod in analogni izhod ter analogni vhod z digitalnim izhodom. Prihodnje revizije standarda bodo zajele digitalne-v/digitalne-iz in analogne-v/analogne-iz preskuse. Ta standard ne velja za slabo stiskanje signala in prav tako ne velja za ojačevalnike moči.
