I think the best explanation and understanding I received about Fourier Transform was from studying linear algebra.

The Fourier Transform equation essentially maps a signal from the time domain onto orthogonal complex sinusoidal basis functions through projection.

And the article does not even mention this. =)

Almost every paragraph of this article says the same thing but in different ways.

What Is the Fourier Transform?
