Fourier transform. It is a calculation by which a periodic function is split up into sine waves.
An asymmetric enlargement. A convolution, Fourier transformation, for example.
A: Any electronics reference book will contain Fourier model transformation. It is just a matter to look them up and which to use for what.
When we do a Fourier transformation of a function we get the primary term which is the fundamental frequency and amplitude of the Fourier series. All the other terms, with higher frequencies and lower amplitudes, are the harmonics.

The Fourier transform is a mathematical transformation used to transform signals between time or spatial domain and frequency domain. It is reversible. It refers to both the transform operation and to the function it produces.
The Fourier series can be used to represent any periodic signal using a summation of sines and cosines of different frequencies and amplitudes. Since sines and cosines are periodic, they must form another periodic signal. Thus, the Fourier series is period in nature. The Fourier series is expanded then, to the complex plane, and can be applied to non-periodic signals. This gave rise to the Fourier transform, which represents a signal in the frequency-domain. See links.
Spatial domain to frequency domain transformation refers to the process of converting an image from its spatial representation (pixels) to its frequency representation (amplitude and phase of different frequencies). This transformation is commonly done using techniques such as Fourier transform, which helps in analyzing an image in terms of its frequency content rather than spatial information.
Fourier series and the Fourier transform
Joseph Fourier was the French mathematician and physicist after whom Fourier Series, Fourier's Law, and the Fourier Transform were named. He is commonly credited with discovering the greenhouse effect.
