"The idea behind the Fourier Transform is that you can express any periodic wave by summing loads of sines with different frequencies. In other words, that you can decompose any wave in a bunch of sines with different frequencies. Of course, when you hear this kind of thing, you should ask two questions:
1- Is it really possible to decompose any periodic wave in sines?
2- Is there an unique decomposition?
