What is a Fourier Series used for? Answer Wiki. The Fourier Transform is used to convert a continuous, periodic time domain signal, into the relative, instantaneous energy contained in the signal, across the entire frequency spectrum, and for *every* moment in time. This is what we call the frequency domain representation of that signal we started with.
The Fourier series is used to represent a periodic function by a discrete sum of complex exponentials, while the Fourier transform is then used to represent a general, nonperiodic function by a continuous superposition or integral of complex exponentials.t can also transform fourier series into frequency domain as fourier series is nothing but a simplified form of time domain PERIODIC function and nothing else. FOURIER SERIES ------------ 1. Periodic function ----------- converts into a DISCRETE exponential or sin cos function.
