Specifically this question.
It's been closed as being too engineering-based, and the Feedback message gave options of other SEs it might fit in. I didn't realise that there was a separate Electrical Engineering SE (although I did choose your electrical-engineering tag, which I suppose means I should have looked!), so it probably would fit better there.
However, whoever closed it didn't migrate it. Is that because:
a. You don't migrate questions
b. You only migrate questions if asked to
c. You do migrate questions, but didn't think the question was good enough
I could just re-write the question on the Electrical Engineering SE, but that seems untidy — it could end up with a closed question here and a successfully answered version elsewhere.
(And I don't know if I should have asked on meta, but couldn't work out how else to do it! I'll delete this later if you want.)
