Abstract

Abstract Translated from German Bei einem Verfahren zur frequenzabhängigen Beeinflus­sung eines Signals wird das Signal nacheinander mehr­mals gefiltert und parallel dazu mehrmals verzögert. Das jeweils gefilterte Signal wird mit je einem zuge­führten Faktor multipliziert und zum entsprechend verzögerten Signal hinzuaddiert. Bei einer Anordnung zur Durchführung des Verfahrens sind für die Filte­rung des Signals digitale Filter (11-1n) mit endlicher Sprungantwort und für die Verzögerung des Signals digitale Allpässe (21-2n) vorgesehen. Die Ausgänge der Fil­ter sind über jeweils einen Multiplizierer (41-4(n-1) mit je­weils einem dem entsprechenden Allpaß nachgeschalte­ten Addierer (51-5n) verbunden. In a method for frequency-dependent influencing of a signal, the signal is filtered several times in succession and delayed several times in parallel. The respective filtered signal is multiplied by a factor supplied and added to the corresponding delayed signal. In an arrangement for carrying out the method, digital filters (11-1n) with a finite step response are provided for filtering the signal and digital all-passes (21-2n) for delaying the signal. The outputs of the filters are each connected via a multiplier (41-4 (n-1) to an adder (51-5n) connected downstream of the corresponding all-pass.
