Abstract
A sub-band splitter unit for splitting a broadband input signal in K narrowband sub-band signals, wherein K is an integer larger than 1, which sub-band splitter unit is provided with an input terminal for receiving the broadband input signal and K−1 sub-band filter circuits, each of the sub-band filter circuits is provided with an input and a first and a second output, a first filter arrangement coupled between the input and the first output, a second filter arrangement coupled between the input and the second output, and the sub-band splitter unit is provided with K output terminals for supplying the K sub-band signals. The first output of a k-th sub-band filter circuit is coupled to an input (.k+1) of the (k+1)-th sub-band filter circuit. The input of the first sub-band filter circuit is coupled to the input of the sub-band splitter unit.
