Introducing Signals and Systems
In This Chapter
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 this book centers on the mathematical modeling of both signals and systems. Mathematical modeling allows an engineer to explore a variety of product design approaches without committing to costly prototype hardware and software development. After you tune your model to produce satisfactory results, you can implement your design as a prototype. And at some point, real signals (and sometimes math-based simulations) test the system design before full implementation.
When studying signals and systems, it’s easy to get mired in mathematical details and lose sight of the big picture — the functional systems of your end result. So try to remember that, at its best, signals and systems is all about designing and working with products through applied math. Math is the means, not the star of the show.
Two broad classes of signals are those that are continuous functions of time t and those that are discrete functions of time index n. Throughout this ...
