|Abstract:||A low complexity high selectivity fast filer bank (FFB) which does not involve down-sampling and up-sampling of signals has been developed in . Since a single sampling rate is used throughout the filtering process, aliasing problem does not exist. In , the FFB was derived from the FFT. In this paper, we present an alternative derivation for the FFB. This alternative derivation renders detail analysis of the performance of the FFB possible. This in turn leads to the optimum design of the FFB. In this paper, we also show by means of an example that the computational complexity of the FFB is significantly less than that of a single-rate polyphase filter.|
