英文摘要：
The generalized H-two filtering problem is studied for a class of networked systems with bandwidth con-straints. The quantized measurement signal is used as the input of the filter. Then, by using the logarithm quantizer, we model the filter-error system as a time-delay system with norm-bounded uncertainty. Sufficient conditions are derived for the asymptotic stability of the filter-error system by the Lyapunov stability theory and the linear matrix inequality （LMI） technique; and the design procedures for the filter are also provided. A numerical example is provided to illustrate the feasibility of the proposed method.
