5.10.2 Factors Determining I/O Temporal Performance
A number of factors control the exact durations of propagation delays. The influence of some of the
factors is, however, ill constrained or unknown. As a consequence, generally valid and exact
quantitative predictions of propagation delays are impossible.
The following factors apply:
Among the insight that can be gained from Ta ble 25 is the fact, that production spread can result in
different propagation delays even for cameras that were produced in one batch and that are
operated under identical conditions.
