Abstract:
The complexity of narrow transition band FIR filters is high and can be reduced by using frequency response masking (FRM) techniques. These techniques use a combination of periodic model filters and masking filters. In this paper, we show that time-multiplexed FRM filters achieve lower complexity, not only in terms of multipliers, but also logic elements compared to time-multiplexed single stage filters. The reduced complexity also leads to a lower power consumption. Furthermore, we show that the optimal period of the model filter is dependent on the time-multiplexing factor.
