Abstract :
This paper deals with allpass frequency transformations of uniform filter banks to achieve nonuniform band-widths. The known transformation with an allpass of first order [1] [4] [5] [6] is extended to an allpass transformation of order K. Thus the flexibility of the filter bank design can be increased significantly.
