science physicsWhy Fourier series is used in communication engineering?
Last Updated: 2nd May, 2020
Communication engineering mainly deal withsignalsand hence signals are of various type likecontinues,discrete,periodic,non-periodic and many of many types.NowFourier transform helps us to converted time domainsignalin frequency domain. Because it allows us to extract thefrequencycomponents of a signal.

Also asked, what is Fourier series used for?
Basically, fourier series is usedtorepresent a periodic signal in terms of cosine andsinewaves.
Subsequently, question is, why do we use Fourier series and Fourier transform? The Fourier series is used to represent aperiodicfunction by a discrete sum of complex exponentials, whiletheFourier transform is then used to represent ageneral,nonperiodic function by a continuous superposition orintegral ofcomplex exponentials.
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
What are the types of Fourier series?
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.
