Abstract :
A variety of digital filter network structures is available. Different network structures posses different quantization properties. The fixed-point roundoff noise and coefficient sensitivity properties of the Swamy-Thyagarajan Wave Digital Filter, the cascade canonic, the Sedlmeyer-Fettweis Wave Digital Filter and the Generalized-Immittance Converter structures are examined in the present paper. The relative power spectral density and the statistical wordlength of each structure are computed.
