Electroacoustics - Octave-band and fractional-octave-band filters - Part 1: Specifications
IEC 61260-1:2014 specifies performance requirements for analogue, sampled-data, and digital implementations of band-pass filters. The extent of the pass-band region of a filter's relative attenuation characteristic is a constant percentage of the exact mid-band frequency for all filters of a given bandwidth. An instrument conforming to the requirements of this standard may contain any number of contiguous band-pass filters covering any desired frequency range. Performance requirements are provided for two filter classes: class 1 and class 2. In general, specifications for class 1 and class 2 filters have the same design goals and differ mainly in the acceptance limits and the range of operational temperature. Acceptance limits for class 2 are greater than, or equal to, those for class 1. Maximum-permitted expanded uncertainties of measurement are also specified. Band-pass filters conforming to the performance requirements of this standard may be part of various measurement systems or may be an integral component of a specific instrument such as a spectrum analyser. This standard specifies the ranges of environmental conditions for operation of the filters. The required range depends on whether the instrument containing the filters is designed to be operated in a controlled environment or more generally in the field. Band-pass filters conforming to the requirements of this standard are capable of providing frequency-band-filtered spectral information for a wide variety of signals, for example, time-varying, intermittent or steady; broadband or discrete frequency; and long or short durations. This first edition of IEC 61260-1, future IEC 61260-2 and future IEC 61260-3, cancel and replace the first edition of IEC 61260 (1995) and its amendment 1 (2001). This edition constitutes a technical revision which includes the following significant technical changes with respect to the IEC 61260 (1995) and its amendment 1 (2001): - the single document in the first edition of IEC 61260 (1995) and its amendment 1 (2001) is in IEC 61260 series separated into the three parts covering: specifications, pattern evaluation tests and periodic tests; - the performance category class 0 is removed; - the design goals for the specification can be based only base-10; - the reference environmental conditions have been changed from 20 °C / 65 % RH to 23 °C / 50 % RH; and - IEC 61260 (1995) specified tolerance limits without considering the uncertainty of measurement for verification of the specifications. IEC 61260 series specifies acceptance limits for the observed values and maximum-permitted uncertainty of measurements for laboratories testing conformance to specifications in the standard.
Elektroakustik - Bandfilter für Oktaven und Bruchteile von Oktaven - Teil 1: Anforderungen
Electroacoustique - Filtres de bande d'octave et de bande d'une fraction d'octave - Partie 1: Spécifications
L'IEC 61260-1:2014 spécifie les exigences de performances des filtres passe-bande analogiques, à données échantillonnées et numériques. L'étendue de la bande passante de la caractéristique d'affaiblissement relatif d'un filtre est un pourcentage constant de la fréquence médiane exacte pour tous les filtres d'une bande passante donnée. Un instrument conforme aux exigences de la présente norme peut contenir n'importe quel nombre de filtres passe-bande adjacents couvrant n'importe quelle gamme de fréquences désirée. Les exigences de performances sont fournies pour deux classes de filtres: classe 1 et classe 2. En général, les spécifications pour les filtres de classe 1 et de classe 2 disposent des mêmes objectifs de conception et diffèrent principalement dans les limites d'acceptation et dans la plage de températures d'exploitation. Les limites d'acceptation de la classe 2 sont supérieures ou égales à celles de la classe 1. Les incertitudes de mesure élargies maximales autorisées sont également spécifiées. Les filtres passe-bande conformes aux exigences de la présente norme peuvent faire partie de différents systèmes de mesure ou peuvent être un composant intégré dans un instrument spécifique tel qu'un analyseur de spectre. La présente norme spécifie les gammes de conditions d'environnement pour le fonctionnement des filtres. La gamme exigée dépend du fait que l'instrument contenant les filtres est conçu pour fonctionner dans un environnement contrôlé ou plus généralement sur le terrain. Les filtres passe-bande conformes aux exigences de la présente norme sont capables de fournir une information spectrale filtrée en bandes de fréquences pour une large variété de signaux, comme des signaux variables dans le temps, intermittents ou permanents, à large bande ou composés de fréquences discrètes, de courtes ou de longues durées. Cette première édition de l'IEC 61260-1 (2014), la future IEC 61260-2 et la future IEC 61260-3, annulent et remplacent la première édition de l'IEC 61260 (1995) et son amendement 1 (2001). Cette édition constitue une révision technique qui inclut les modifications techniques majeures suivantes par rapport à l'IEC 61260 (1995) et son amendement 1 (2001): - le document unique dans la première édition de l'IEC 61260 (1995) et son amendement 1 (2001) est, dans la série IEC 61260 divisé selon les trois parties suivantes: spécifications, essais d'évaluation d'un modèle et essais périodiques; - l'IEC 61260-1 (2014) ne contient plus de catégorie de performances de classe 0; - dans l'IEC 61260-1 (2014), les objectifs de conception de la spécification sont basés sur une conception en base 10 uniquement; - les conditions d'environnement de référence sont passées de 20 °C / 65 % d'humidité relative à 23 °C / 50 % d'humidité relative; - l'IEC 61260 (1995) et son amendement 1 (2001) spécifiait des limites de tolérance sans considérer l'incertitude de la mesure pour la vérification des spécifications. La nouvelle série IEC 61260 spécifie des limites d'acceptation pour les valeurs observées et l'incertitude maximale autorisée des mesures pour la conformité des essais de laboratoire aux spécifications de la norme.
Elektroakustika - Oktavni in frakcijski oktavni filtri - 1. del: Specifikacije (IEC 61260-1:2014)
Standard EN IEC 61260-1 določa zahteve glede zmogljivosti za analogne in digitalne izvedbe ter izvedbe z vzorčenimi podatki pasovnoprepustnih filtrov. Obseg območja pasovne širine značilnosti relativnega slabljenja filtra je stalen odstotek točne medpasovne frekvence za vse filtre določene pasovne širine. Instrument, ki je v skladu z zahtevami iz tega standarda, lahko vključuje poljubno število sosednjih pasovnoprepustnih filtrov, ki zajemajo katero koli želeno frekvenčno območje. Zahteve glede zmogljivosti so navedene za dva razreda filtrov: razred 1 in razred 2. Na splošno imajo specifikacije za filtre razreda 1 in razreda 2 enake cilje glede zasnove ter se razlikujejo predvsem v mejah sprejemljivosti in razponu delovne temperature. Meje sprejemljivosti za razred 2 so večje ali enake mejam sprejemljivosti za razred 1. Opredeljene so tudi največje dovoljene razširjene negotovosti pri merjenju. Zahteve glede zmogljivosti so navedene za zasnove z oktavnim frekvenčnim razmerjem in medpasovnimi frekvencami na deseto potenco. Pasovnoprepustni filtri, ki so v skladu z zahtevami glede zmogljivosti iz tega standarda, so lahko del različnih merilnih sistemov ali pa so ključna komponenta posebnega instrumenta, kot je spektralni analizator. Ta standard določa razpone okoljskih pogojev za delovanje filtrov. Zahtevani razpon je odvisen od tega, ali je instrument, ki vsebuje filtre, oblikovan za delovanje v nadzorovanem okolju ali splošneje v polju. Pasovnoprepustni filtri, ki so v skladu z zahtevami tega standarda, so sposobni zagotavljati spektralne informacije, filtrirane po frekvenčnem pasu, za raznolike signale, na primer časovno spremenljive, občasne ali neprekinjene; širokopasovne ali diskretne frekvence; in z dolgim ali kratkim trajanjem.
