Abstract

Ein Signal, das neben den eigentlich interessierenden Signalkompenenten auch ungewünschte Rauschkomponenten enthält, wird, sofern es nicht bereits in digitaler Form gemessen wurde, zunächst an den Eingang eines analog-digital-Wandlers gelegt, der einen Satz diskreter Daten erzeugt. Die diskreten Daten werden gespeichert, und Sätze der gespeicherten Daten werden sequentiell von einem adaptiven sogenannten 'Gleitender-Durchschnitt-Glättungs-Filter' verarbeitet, der für jeden diskreten Eingangswert einen rückabgeschätzten Wert erzeugt. Der erhaltene rückabgeschätzte Wert wird mit dem entsprechenden diskreten Eingangswert verglichen und als Resultat des Vergleichs wird der genannte Filter iterative abgeglichen, so daß die Differenz zwischen den Eingangswerten und den rückabgeschätzten Werten einen vorgegebenen Grenzwert nicht überschreitet.
