Clipping (signal processing)
Clipping is a form of distortion that limits a signal once it exceeds a threshold. Clipping may occur when a signal is recorded by a sensor that has constraints on the range of data it can measure, it can occur when a signal is digitized, or it can occur any other time an analog or digital signal is transformed, particularly in the presence of gain or overshoot and undershoot. Clipping may be described as hard, in cases where the signal is strictly limited at the threshold, producing a flat cutoff; or it may be described as soft, in cases where the clipped signal continues to follow the original at a reduced gain.
Analyse des systèmes de mesure
L'analyse des systèmes de mesure (anglais : measurement system analysis) est un processus d'évaluation d'un système de mesure (les instruments, les méthodes de test, les conditions, etc.) pour en déterminer la qualité, mais aussi la capabilité en vue d'une application donnée. Elle joue donc un rôle important dans la métrologie industrielle, la gestion de la qualité et les démarches associées.
