Fourier Analysis

Fourier analysis is a method of representing general functions by the approximate sum of simple trigonometric functions. 


The method is named after mathematician Jean Baptiste Joseph Fourier who formulated and proved the Fourier series. 


Fourier analysis is used in electronics, communications, and acoustics.


The method gets its name from a French mathematician and physicist named Jean Baptiste Joseph, Baron de Fourier, who lived during the 18th and 19th centuries. 

Fourier analysis is used in electronics, acoustics, and communications.


In Fourier analysis, the objective is to calculate coefficients aa 1, a 2, a 3, ..., an n and b 1, b 2, b 3, ..., bn up to the largest possible value of n

The greater the value of n (that is, the more terms in the series whose coefficients can be determined), the more accurate is the Fourier-series representation of the waveform.
