Abstract (en)
[origin: EP2190218A2] The filter bank system has an analysis filter bank for analyzing the input signals in partial band signal. A stop-band attenuation (12) assembles one of a transmission function of analysis filter bank from a separately configured, frequency dependent analysis-base attenuation fraction and separately configured, frequency dependent analysis attenuation fractions (10,11). A synthesis filter bank is provided for assembling a manipulated partial band signal with another partial band signal.
