| Zusammenfassung: | The invention relates to an apparatus and a method for detecting and correcting input signals regarding click noise, using a first detector unit (2,21) unit and a second correction unit (3,22), the detector unit (2,21) differentiates the input signal (4,23) and extracts the noise signal (6) and compares (8,33) the sum of two noise samples with a threshold value (35/T 2 ) and in case this sum exceeds the threshold value (35/T 2 ) a click is observed, while the correction unit (3,22) corrects (9) the input signal (4,23) in the phase domain and differentiates (11) it prior to outputting the corrected signal. |
