IEC 60469-ed.1.0

Annotation of standard text IEC 60469-ed.1.0 :

IEC 60469:2013 provides definitions of terms pertaining to transitions, pulses, and related waveforms and provides definitions and descriptions of techniques and procedures for measuring their parameters. The waveforms considered in this standard are those that make a number of transitions and that remain relatively constant in the time intervals between transitions. Signals and their waveforms for which this standard apply include but are not limited to those used in: - digital communications, data communications, and computing; - studies of transient biological, cosmological, and physical events; - and electrical, chemical, and thermal pulses encountered and used in a variety of industrial, commercial, and consumer applications. This standard does not apply to sinusoidally-varying or other continuously-varying signals and their waveforms. The object of this standard is to facilitate accurate and precise communication concerning parameters of transitions, pulses, and related waveforms and the techniques and procedures for measuring them. IEC 60469:2013 combine the contents of IEC 60469-1 and IEC 60469-2. IEC 60469-1 dealt with terms and definitions for describing waveform parameters and IEC 60469-2 described the waveform measurement process. Other technical revisions include updating of terminology, errors correction, algorithms addition for computing values of pulse parameters, and addition of a newly-developed method for computing state levels. Changes to the definitions include adding new terms and definitions, deleting unused terms and definitions, expanding the list of deprecated terms, and updating and modifying existing definitions. La CEI 60469:2013 definit des termes relatifs aux transitions, impulsions et formes dondes associees, puis definit et decrit plusieurs techniques et procedures de mesure des parametres correspondants. Les formes dondes abordees dans la presente norme sont celles qui presentent un certain nombre de transitions et restent relativement constantes dans lintervalle de temps separant les transitions. Les signaux et formes dondes associees auxquels la presente norme sapplique comprennent, sans sy limiter, ceux utilises dans: - les communications numeriques, les communications de donnees et linformatique; - letude des evenements biologiques, cosmologiques et physiques transitoires; - ainsi que les impulsions electriques, chimiques et thermiques rencontrees et utilisees dans diverses applications industrielles, commerciales et grand public. La presente norme ne concerne pas les signaux a variation sinusoidale et autres signaux a variation continue, ni leurs formes dondes associees. La presente norme a pour objet, dune part, de faciliter une communication precise et claire quant aux parametres des transitions, des impulsions et des formes dondes associees, dautre part, de definir les techniques et procedures permettant de les mesurer. La CEI 60469:2013 vise a combiner le contenu des normes CEI 60469-1 et CEI 60469-2. La CEI 60469-1 traitait des termes et definitions visant a decrire les parametres de forme donde, et la CEI 60469-2 decrivait le procede de mesure des formes dondes. Dautres mises a jour techniques incluent lactualisation de la terminologie, la correction derreurs, lajout des algorithmes de calcul des valeurs de parametres dimpulsion et lintroduction dune nouvelle methode de calcul des niveaux detat. Les modifications apportees aux definitions comprennent lajout de nouveaux termes et definitions, la suppression de termes et definitions inutilises, lextension de la liste des termes deconseilles, de meme que lactualisation et la modification des definitions existantes.
