For an explanation of the Fourier transform, the following link: It's very detailed:

Note the point:

1, signal processing based on such a concept, the signal to be processed (? ) can be decomposed into sine wave, different amplitude, different phase, different frequency, such as: F=cos (W1*T+Π/4) +100cos (W2*T+Π/6)

2, by decomposition to convert it to a different signal of the composition of how many representations, that is, its side of the diagram.
