Abstract :
Cascaded integrator comb (CIC) filters are used to realize computationally efficient decimation, interpolation or sample rate conversion. However, since CIC filters have a limited number of tuning parameters and exhibit a passband droop, their use in software defined radio (SDR) systems may be limited. In this paper, we propose an alternative structure to CIC filters that, at the expenses of a higher computational effort, is suitable for SDR systems
