I'm writing software and the data reporting frequency is slower than the acquisition cycle, so effectively sub-sampling is being done. Different data types require different methods of sub-sampling which I'm tempted to call a
Gating method where oversampled data in one time domain goes through a
Gate to another time domain.
Windowing also comes to mind.
I hesitate though as although these terms imply an interval of focus/ interest, they might not necessarily imply continuity between intervals; back to back intervals where no input is ignored.
Such methods might be:
- Average/Median since last report (or low pass filter)
- Min/Max since last report
- Sticky flags (a bit field who's bits are cleared when read)
Is there a better term than
Note 1: This is borderline a programming question or code review, but I think still more for signal processing.
Note 2: Although sub-sampling causes signal artifacts such as aliasing. This is not part of the question.
