device has filters in an analysis filter bank and corresponding filters in a synthesis filter bank that are coupled pair wise to form a channel in each case in order to compensate for a hearing loss sub band signals are amplified in the individual channels with the aid of multipliers in the process an audible distortion of an output signal y of the filter bank configuration as a result of differences between amplification factors of the multipliers of neighboring channels should be prevented here at least one channel changes a phase of a sub band signal transmitted by the channel such that a difference between a group delay of the filter bank configuration and a prescribable reference value is reduced for at least one predetermined frequency the filter bank configuration is particularly suited to hearing aids application_number US 83317110 A description referring now once more to the figures of the drawing in detail fig4 shows a diagram with a graph of a group delay u03c4 u03c9 wherein the axes of the diagram correspond to the axes of the diagram illustrated in fig3 in terms of design these two filter banks correspond to the filter bank illustrated in fig2 here the filter bank in fig4 consists of a complex modulated polyphase filter bank with h 1 as a prototype low pass filter the band pass filters h 2 to h i correspond in their amplitude response to the filter h 1 wherein however the central frequency of a pass band has in each case been displaced to a frequency u03c9 2 u03c0 1 u2212 1 i by a complex modulation in contrast to the filter bank that is the basis of the graph in fig3 the filter bank belonging to the.
