The Fourier transform It is a fundamental mathematical operation for some disciplines such as telecommunications or physics. Without it, modern telecommunications would not exist, not only the Internet or mobile telephony, but also conventional telephony, which could not have evolved beyond a form of local communication and long distance calls would not have existed.
Although this mathematical operation owes its name to the mathematician Joseph Fourier, the truth is that many have contributed to its invention, including Euler, Bernoulli, Lagrange and Gauss. Fourier played an essential role, inventing the Fourier series, where a periodic function could be decomposed into the sum of trigonometric functions. The Fourier transform generalizes this concept.
