How did Fourier come up with the Fourier series?
Fourier, a French military scientist, became interested in heat transfer in the late 1790s. During this time, his obsession with heat transfer drove him to derive an equation describing the conduction of heat in solid bodies. Within seven years, he invented the Fourier transform to solve this equation.

Where does the Fourier transform come from?
The Fourier transform of a Gaussian function is another Gaussian function. Joseph Fourier introduced the transform in his study of heat transfer, where Gaussian functions appear as solutions of the heat equation.

What did Joseph Fourier discover?
Jean Baptiste Joseph Fourier (1768-1830), French mathematician and natural philosopher, did groundbreaking work in mathematics and the theory of heat. He was the first to propose that the Earth’s atmosphere acts to raise the planet’s temperature.

What does fourier series represent?
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. A sawtooth wave represented by a successively larger sum of trigonometric terms.
What is Fourier series and why it is used?
Fourier series is just a means to represent a periodic signal as an infinite sum of sine wave components. A periodic signal is just a signal that repeats its pattern at some period. The primary reason that we use Fourier series is that we can better analyze a signal in another domain rather in the original domain.
What is important about a Fourier series?
The Fourier series is a good stepping stone toward the Fourier transform. Sound processing is probably the purest and simplest application. Fourier series are important for understanding Fourier Transforms which is one of the most basic elements of signal processing of all sorts (including Khashishi’s sound processing).
What did Fourier invent?
The Fourier Transform is a method of decomposing the life of an individual into a linear combination of sins and cos’s (pronounced causes). Pope Jean-Baptiste Joseph Fourier XII invented the transform as a method of efficiently passing information to God for use during the Final Judgment.
Why to use the Fourier series?
The primary reason that we use Fourier series is that we can better analyze a signal in another domain rather in the original domain. Sometimes a signal reveals itself more in another domain.
