Störungsbeseitungsvorrichtung and troubleshooting program
2010
A troubleshooting unit (102) performs a fault clearance and Flooringverarbeitung with an input signal through, and a density calculation unit (104) calculated with respect to a point of interest in a time-frequency plane of the input signal which has been subjected to the noise cancellation, a density of Nichtflooringverarbeitungspunkten reference to the presence or absence of Flooringverarbeitung of individual points around the interest point. A partial suppression unit (105) replaces, if the density is less than a threshold, the energy of the interest point by its Flooringwert by considering this as a musical noise component, whereby the musical noise component is suppressed.
