摘要：
A technique is presented for the design of mulliplierless FIR filters with canonical signed digit (CSD) coefficients based on higher-order Sigma-Delta modulation with a CSD quantiser (Sigma-Delta-CSD). The proposed algorithm requires little computational resources and is capable of designing more types of filters and providing better performance than the previously proposed first-order method.
