Vorrichtung und Verfahren zum Verarbeiten eines Eingangssignals

WO2005046194 A UPAB: 20050704 NOVELTY - The processing device has a device (101) for providing a number of wave field components forming a wave field able to propagate in the space and a number of individual filters (107) for influencing the wave field components to produce filtered wave field components representing a processed input signal. The number of wave field components is derived by breaking down the wave field based on orthogonal functions and the geometric positions DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (A) a device for detecting a transmission characteristic (B) a device for detecting an inverse transmission characteristic (C) a device for generating a prediction error signal (D) a device for recovering a useful signal from an input signal (E) a device for suppressing a noise component (F) a method of processing an input signal (G) a method of actively suppressing noise in a stimulation signal (H) and a computer program for implementing the inventive method. USE - For processing an input signal. ADVANTAGE - Enables the processing of continuous wave fields that are able to propagate in a space
