Ich habe bezüglich der besprochenen Fragen untenstehende Infos erhalten.
Bis heute Abend

p11 Q4: Is the didactic intent of the question to recognize real
execution order as to the DAQmx call overriding "Elapsed Timer" at runtime?
Purpose is being aware of order of execution and being able to follow the function and logic. Basically recognize the size of the "chunks" of data and how many chunks will be collected (how many times the read will happen).
p22 Q4: My students reproduced possible solution code A & D and both
rendered the result asked for. Is that intended?
Not sure how they managed that, adding the two 1D arrays produces a 1D array of the wave produced when two sine waves are added, while D (correct answer) writes both arrays to the same graph. Would you like to send me their VIs?
p23 Q7: Is anyone in the NXG team aware of the nondeterministic rounding
effects when entering values like 1.5 and 2.5 !? Sure enough the
coercion dot indicates danger, but why would such behavior span across
LV2016 up to NXG!?
LabVIEW follows IEEE standards for rounding. See http://zone.ni.com/reference/en-XX/help/371361H-01/glang/round_to_nearest/
The coercion dot indicates that LabVIEW has shifted (or coerced) the data type, which might be OK but is something you'll want to be aware of for a couple of reasons.
