Abstract

Ein Verfahren zur Identifikation eines zeitlich veränderlichen Übertragungsverhaltens eines bandbegrenzten Systems, bestehend aus einem Sendewandler, einem Empfangswandler und der zugehörigen Elektronik, sieht vor, dass die Übertragungsfunktiondes Systems durch Analyse der Übertragung eines Signals größerer Bandbreite als die Systembandbreite bestimmt wird, und dass ein parametrisches Modell der Übertragungsfunktion gebildet wird und die Modellparameter mittels Fitverfahren bestimmt werden.
