I've never seen this terminology before. Is this standard math parlance or
is it something of your own?

You can google for it (Usenet or Web) and find it, I've seen it
used a good bit in signal processing and such.

And it shows up in some math classes as well, though its main use is
in electronics. I suspect it showed up because the instructor wanted
to show a real-life example, which just happened to be -- electronics.
