res and possible solutions for the linearity problem of theDA converter in the feedback loop of converters. .Several circuit design aspects of multi-bit Delta-Sigma converters arediscussed. Various models are provided for a wide range of linear andnon-linear circuit imperfections, which can degradeHemoptysis 发表于 2025-3-23 23:41:09

Justin Greenwoodtrol groups that appear comparable in terms of a specific list of measured covariates – groups that are ostensibly comparable – may nonetheless differ in terms of covariates that were not measured. Though not discussed in the current chapter, the important issue of unmeasured covariates in this examcancellous-bone 发表于 2025-3-24 21:02:46

r in large samples of a sensitivity analysis is used to judge the ability of design features, such as those in Chapter 5, to distinguish treatment effects from bias due to unmeasured covariates. As the sample size increases, the limit of the power of a sensitivity analysis is a step function with a
