Abstract
A filter bank system that is optimized with respect to group delay and power consumption is provided. The filter bank system has multiple levels and has an input-side and an output-side filter bank based on a defined filter type. The input-side filter bank has input channels as a variable first parameter, and an oversampling factor as a variable second parameter. For optimizing the multilevel filter bank, a group delay and an operation rate are now respectively determined for each of a plurality of value pairs of the first and second parameters. The value pair for which the associated group delay and the associated operation rate satisfy a defined criterion, in particular for which they are as low as possible, is selected from the value pairs. The input-side filter bank is subsequently configured with the number of channels and the oversampling factor corresponding to the selected value pair.
