In conventional filter banks, the sampling factors are restricted to rational numbers and frequency partition is always rather inflexible, stemming from the fact that certain constraint on each subband position is always placed. In this paper, we present a class of M-channel nonuniform filter banks with arbitrary sampling factors including integer, rational, and even irrational numbers. Consequently, the frequency partitioning in the proposed filter bank is much more flexible, which is very attractive in many applications.
