How do you convert a signal from its temporal domain representation to its frequency domain representation?

@zyl It should be pretty easy to do this through inspection for a simple function like the sum of two sinusoids. For more complex signals though, we often use the Fourier transform described on this slide to go from the spatial (temporal) domain to the frequency domain, or the other way around. The spectrum shown here is simply the absolute value of the Fourier transform of the function.
