Coherence (signal processing) (original) (raw)

Property Value
dbo:abstract Die Kohärenzfunktion ist ein Maß für den Grad der linearen Abhängigkeit zweier Zeitsignale und über der Frequenz. Sie ist mathematisch gesehen nichts anderes als das Betragsquadrat des normierten mittleren Kreuzleistungsspektrums. Sie berechnet sich nach der Gleichung . (de) In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the causality between the input and output. (en)
