Can you guess what that signal is?

...OK, I give up, what is it?

vss?

I'm sorry, all I could think about when I read this was that new tv show "Big Bang". This could be one of the games they play: "Guess This Waveform".:D

No correct guesses yet. Please keep guessing.

Something to do with organic chemistry?

Technically, yes. But not really.

Me calling from what I think you on this planet call Mars ?

...hmm-m-m-m, that sorta points toward gasoline...maybe injector pulses?

...but, if true, then they're awfully "ratty" looking.

...I'd expect a 'drive' signal to be fairly "clean" looking, while a "return" signal could be "ratty" due to added noise.
