Comparison of the effects of quantization on digital filters
J. Lam, V. Ramachandran, M.N.S. Swamy · IEEE Transactions on Acoustics Speech and Signal Processing · 1982
The fixed-point roundoff noise and coefficient sensitivity properties of the cascade canonic, Sedlmeyer-Fettweiss wave digital filter, the digital generalized immittance converter filter, and the Swamy-Thyagarajan wave digital filter are examined. The relative power spectral density and the statistical wordlength of each structure are computed.
