Finite Word-Length Effects in Digital State-Space Filters

The state-space description of digital filters involves except the relationship between input and output signals an additional set of state variables. The state-space structures of digital filters have many positive properties compared with direct canonical structures. The main advantage of digital filter structures developed using state-space technique is a smaller sensitivity to quantization effects by fixed-point implementation. In our presentation, the emphasis is on the analysis of coefficient quantization and on existence of zero-input limit cycles in state-space digital filters. The comparison with direct form II structure is presented

Investigation of the first reported outbreak of New Delhi metallo-β-lactamase-1-producing Pseudomonas aeruginosa in Texas

We describe an epidemiologic investigation and successful control measures for the first reported outbreak of blaNDM-1-carrying Pseudomonas aeruginosa in Texas occurring in a veteran with transmission of the same organism and a blaNDM-5-carrying Escherichia coli, respectively, to two roommates and blaNDM-carrying organism/s to a patient cared for by common staff
