Which came first: the signal or the system? Before you answer, you may want to know that by system, I mean a structure or design that operates on signals. You live and breathe in a sea of signals, and systems harness signals and put them to work. So which came first, you think? It may not really matter, but I’m guessing — as I smooth out a long imaginary philosopher-type beard — that signals came first and then began passing through systems.
But I digress. The study of signals and systems as portrayed in ...
