摘要：
This paper proposes a novel variable structure for linear phase frequency-selective maximally flat FIR digital filters. The proposed method expresses the transfer function by cascading and paralleling the 2nd order variable subfilters. The multiplier of the subfilter requires very few multiplication in update compared with the conventional maximally flat variable FIR digital filters. Hence, the proposed structure can change the frequency response immediately.
