Trigonometry - Fourier (Analysis|Synthesis)
Fourier analysis is the study of the way general functions may be represented or approximated by sums of simpler trigonometric functions.
In the sciences and engineering,:
- the process of decomposing a function into simpler pieces is often called Fourier analysis (Fourier transform)
- while the operation of rebuilding the function (the inverse Fourier transformation) from these pieces is known as Fourier synthesis.
