science physicsWhy Fourier series is used in communication engineering?
Also asked, what is Fourier series used for?
Basically, fourier series is usedtorepresent a periodic signal in terms of cosine andsinewaves.
Subsequently, one may also ask, why Fourier transform is used in communication?
In the theory of communication a signalisgenerally a voltage, and Fourier transform isessentialmathematical tool which provides us an inside view ofsignal andits different domain, how it behaves when it passesthrough variouscommunication channels, filters, andamplifiers and it alsohelp in analyzing various
Four different forms of Fourier transform.Allpreviously discussed Fourier series expansionsandtransforms of various types of signals (periodic,aperiodic,continuous, discrete) can be considered as differentforms(special cases) of the same Fourier transform,and therebyunified.
