Abstract: | It is shown that non-critically-sampled uniform filter banks have an efficient implementation, consisting of an FFT processor, and a time-varying structure derived from the prototype filter polyphase network. It is also shown how DFT filter bank optimisation techniques can be applied in the general case.<> |
