Fourier Series

A Fourier series (/ ? f ?r i e?,-i ?r /) is a sum that represents a periodic function as a sum of sine and cosine waves. The frequency of each wave in the sum, or harmonic, is an integer multiple of the periodic function's fundamental frequency.Each harmonic's phase and amplitude can be determined using harmonic analysis.A Fourier series may potentially contain an infinite number of harmonics.

A Fourier series is an expansion of a periodic function f(x) in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions. The computation and study of Fourier series is known as harmonic analysis and is extremely useful as a way to break up an arbitrary periodic function into a set of simple terms that can be ...

Storia. La serie prende il nome dal matematico francese Joseph Fourier (1768-1830), il quale fu il primo a studiare sistematicamente tali serie infinite.In precedenza esse erano state oggetto di investigazioni preliminari da parte di Eulero, d'Alembert e Daniel Bernoulli.Fourier applicò tali serie alla soluzione dell'equazione del calore, pubblicando i suoi risultati iniziali nel 1807 e nel 1811.

A Fourier series is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the ...

The Fourier series can be defined as a way of representing a periodic function (possibly infinite) as a sum of sine functions and cosine functions. The Fourier series is known to be a very powerful tool in connection with various problems involving partial differential equations.

A Fourier series is a sum of sine and cosine waves that represents a periodic function. Each wave in the sum, or harmonic, has a frequency that is an integer multiple of the periodic function’s fundamental frequency. Harmonic analysis may be used to identify the phase and amplitude of each harmonic. A Fourier series might have an unlimited ...
