I noticed today that we've got at least two distinct classes of question using the filters tag:
- Mechanical filtration questions, e.g.
- Signal processing questions, e.g.
There's also one that seems to involve concepts of both.
There are also quite a few questions where the tag is absent but could potentially be added; of these, I see around 5 that might use the tag in a mechanical filtration context and 7-8 that might use it in a signal processing context.
It seems clear that we need to be filtering these questions into multiple tags. I'm not sure whether two tags be enough to provide effective categorization, or if we should further subdivide the signal-related questions into smaller domains; for example, acoustic versus EM.
How can we best categorize these questions?
Please think about how any proposed tags could be distinguished using tag wiki excerpts, and whether we need any tag synonyms to support a particular set of tags.
