Fourier series in Engineering Sciences

The relatively complicated theory of Fourier series, but the series is simple to use. Fourier series, Taylor series is more comprehensive because many discrete periodic functions that are of practical importance to the Fourier series expansion, but not Taylor expansion. Numerous problems in science and engineering that results in a series and Fourier sine signals, plays a major role in them.
Since all receptors in electrical engineering, send and processors sine and cosine wave signals operate on the basis of the elements required to signals in the form of sine and cosine signals out there that almost do not know this form. But in practice sine and cosine signals are reasons to form. For example, signals sent from a satellite in space because of the noise the way, whether from sunlight, magnetic field of gravity, magnetic field created by the human hand in the atmosphere, weathering and other problems, including of dissociation, defined Uninsured, integral and derivative etc., while a signal with this conditions for receiver and processor circuitry is incomprehensible. To solve these problems we use the Fourier series. In this study, Fourier series and its applications in industry and engineering sciences is evaluated.
