Abstract :
A technique is presented for the design of multiplierless FIR filters with canonical signed digit (CSD) coefficients based on higher-order Σ-Δ modulation with a CSD quantiser (Σ-Δ-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
