The fast filter bank (FFB) describes a class of tree-structured filter banks that operate on a frequency response masking principle. Although the structure is highly regular and conveniently implemented in hardware designs, real-time software implementations lead to inefficiencies due to its branching structure. In this paper, an alternative formulation of… (More)
The Fast Filter Bank has a very low single-rate computational complexity, but is however limited to having powers-of-two number of output channels. In this paper, a new mixed-radix architecture is proposed that allows an arbitrary number of output channels to be implemented.
