Transitions, pulses and related waveforms - Terms, definitions and algorithms
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.

Transitions, impulsions et formes d'ondes associées - Termes, définitions et algorithmes
La CEI 60469:2013 définit des termes relatifs aux transitions, impulsions et formes d'ondes associées, puis définit et décrit plusieurs techniques et procédures de mesure des paramètres correspondants. Les formes d'ondes abordées dans la présente norme sont celles qui présentent un certain nombre de transitions et restent relativement constantes dans l'intervalle de temps séparant les transitions. Les signaux et formes d'ondes associées auxquels la présente norme s'applique comprennent, sans s'y limiter, ceux utilisés dans: - les communications numériques, les communications de données et l'informatique; - l'étude des événements biologiques, cosmologiques et physiques transitoires; - ainsi que les impulsions électriques, chimiques et thermiques rencontrées et utilisées dans diverses applications industrielles, commerciales et grand public. La présente norme ne concerne pas les signaux à variation sinusoïdale et autres signaux à variation continue, ni leurs formes d'ondes associées. La présente norme a pour objet, d'une part, de faciliter une communication précise et claire quant aux paramètres des transitions, des impulsions et des formes d'ondes associées, d'autre part, de définir les techniques et procédures permettant de les mesurer. La CEI 60469:2013 vise à combiner le contenu des normes CEI 60469-1 et CEI 60469-2. La CEI 60469-1 traitait des termes et définitions visant à décrire les paramètres de forme d'onde, et la CEI 60469-2 décrivait le procédé de mesure des formes d'ondes. D'autres mises à jour techniques incluent l'actualisation de la terminologie, la correction d'erreurs, l'ajout des algorithmes de calcul des valeurs de paramètres d'impulsion et l'introduction d'une nouvelle méthode de calcul des niveaux d'état. Les modifications apportées aux définitions comprennent l'ajout de nouveaux termes et définitions, la suppression de termes et définitions inutilisés, l'extension de la liste des termes déconseillés, de même que l'actualisation et la modification des définitions existantes.
Prehodi, impulzi in z njimi povezane valovne oblike - Izrazi, definicije in algoritmi (IEC 60469:2013)
Ta mednarodni standard podaja opredelitve izrazov s področja prehodov, impulzov in z njimi povezanih valovnih oblik, ter podaja opredelitve in opise tehnik ter postopkov za merjenje njihovih parametrov. Valovne oblike, vključene v ta standard, so tiste, ki ustvarijo več prehodov in ostanejo v časovnih intervalih med prehodi relativno stanovitne. Signali in njihove valovne oblike, za katere velja ta standard, med drugim vključujejo tiste, ki se uporabljajo na področju: digitalnih komunikacij, podatkovnih komunikacij in računalništva; študij prehodnih bioloških, kozmoloških in fizičnih dogodkov; ter električnih, kemijskih in toplotnih impulzov, ki nastajajo in se uporabljajo za različne industrijske, komercialne in potrošniške uporabe. Ta standard se ne uporablja za sinusno različne ali druge nenehno spreminjajoče se signale in njihove valovne oblike. Namen tega standarda je omogočiti natančno komunikacijo glede parametrov prehodov, impulzov in z njimi povezanih valovnih oblik ter tehnik in postopkov za njihovo merjenje.
