Fourier analysis began with trying to understand when it was possible to represent general functions by sums of simpler trigonometric functions. The attempt to understand functions (or other objects) by breaking them into basic pieces that are easier to understand is one of the central themes in Fourier analysis. Fourier analysis is named after Joseph Fourier who showed that representing a function by a trigonometric series greatly simplified the study of heat propagation. If you want to find out more, look up fourier synthesis and the fourier transform.
Fourier series is the sum of sinusoids representing the given function which has to be analysed whereas discrete fourier transform is a function which we get when summation is done.
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
A Fourier series is a set of harmonics at frequencies f, 2f, 3f etc. that represents a repetitive function of time that has a period of 1/f. A Fourier transform is a continuous linear function. The spectrum of a signal is the Fourier transform of its waveform. The waveform and spectrum are a Fourier transform pair.

Fourier series and the Fourier transform
Joseph Fourier was born on March 21, 1768.
Joseph Fourier was born on March 21, 1768.
Joseph Fourier University was created in 1811.
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.
The name of Joseph Fourier's wife is not known. Joseph Fourier was a historian, mathematician and physicist. He is most known for discovering the greenhouse effect.
Joseph Fourier died on May 16, 1830 at the age of 62.
Joseph Fourier died on May 16, 1830 at the age of 62.
An interesting fact about Joseph Fourier is that he discovered the greenhouse effect. He was the scientific adviser to Napoleon when he traveled to Egypt.
Joseph Fourier was born on March 21, 1768 and died on May 16, 1830. Joseph Fourier would have been 62 years old at the time of death or 247 years old today.
Joseph Fourier was trained at Ecole Normale Superieure. He was a top mathematician and scientist and a personal assistant to Napoleon Bonaparte.
