Is Fourier series in time or frequency domain?
The Fourier transform is the primary tool for analyzing signals and signal-processing systems in the frequency domain, especially when signals are sampled or converted from discrete time to continuous time.
What is the relation between time domain and frequency domain?
Parseval's theorem gives the relationship between the squared integral of a time function and that of its Fourier transform, namely, the energy in the time domain is equal to the energy in the frequency domain.
What is Fourier series in frequency domain?
A Fourier series (/ˈfʊrieɪ, -iər/) is a summation of harmonically related sinusoidal functions, also known as components or harmonics.
Is Fourier a frequency domain?
The term Fourier transform refers to both the frequency domain representation and the mathematical operation that associates the frequency domain representation to a function of space or time.
