I remember that Fourier series was for periodic and transform was for non-periodic, and I remember the formulas for the series coefficients and the transform and inverse transform equations. But what I can't remember is, say you have a picture, or lests go simpilar than that and say a wave.

I assume you can say that anything, any complex snipit of a signal, is periodic, even if it isn't, and just discard the rest of the series? For instance:

Another way of putting this questions is: is the can you take the series of a non-periodic and just discard the rest of the series? Instead of the transform; turning anything into a periodic series.

But also, say you had that signal, on some scale so you could see time and amplitude, how do you actually know what the

*f(t)*Because you need

__is__?__that__to calculate the transform or series?

If you've just got some signal, how do you know what you're actually opperating on to get the coefficients or do the transform?
