"Drive the transducer cable shield, S, with the common mode signal source […] to reduce the effective cable capacitance, as fig. 15-3 shows. [p. 218 ]" How does the guard reduce the effective cable capacitance? There’s C dv/dt. C remains the same. dv/dt also remains the same, because driving the shield with the common mode voltage [aka guarding] is a DC action.

Discussion of hot wire anemometers on pp. 205-207 .

ch.8 pp.157-158 discussion about large binary files in version control systems. Large binary files can’t be stored as incremental diffs, which slows down version control operations. The book has it in a context of 3rd party libraries, although this would apply to binary CAD and EDA files too. The book proposes a schemes where VCS knows library version and enforces compatibility without storing the binary (p.158).

ch.6 p.124 the introduction to Components of Large Systems section. It describes two models of software development: free and commercial. Nice passage.

Three chapters 11 though 13 (pp. 177-235) are dedicated to test benches.

Good chapters so far: chapter 2 about simulation, chapter 9 modeling style and case studies
