On the above link you show two sinewaves figure3a, 3b. The first is a nice sinewave, the second stepped.
If you use two different types of presentation then you can prove everything.
Or you use stepped sinewaves on both, or you use markers to point out the time the sample was taken.
ps:
I always thought the cFP2020 had a cpu clock of 200MHz?
Have program a realtime simulator for powerplants written in C++.I translates the RT sim to NI components and software (Labview).
My rt pxi turbine simulator for simulating grid incidents was succesfully used in a nuclear plant in 2006.
