A Note on the 2-D Noise Matrix of 2-D State-Space Digital Filters

Tao Lin, Masayuki Kawamata

Research output: Contribution to journal › Article › peer-review

Abstract

The formulas by Lin, Kawamata, and Higuchi [1] to compute the output noise and the noise matrix (observability Gramian) of 2-D digital filters are different from the formulas by Lu and Antoniou [2]. This letter shows that the derivation of the formulas by Lu and Antoniou is incorrect.
