Question

What is Fourier series in signal processing?

Answer 1

Answer:

In signal processing, the Fourier transform often takes a time series or a function of continuous time, and maps it into a frequency spectrum. ... The magnitude of the resulting complex-valued function F at frequency ω represents the amplitude of a frequency component whose initial phase is given by the phase of F.

Answer 2

Answer:

$\qquad\qquad\underline{\textsf{\textbf{ \color{purple}{AnSwEr} }}}$

The Fourier series synthesis equation creates a continuous periodic signal with a fundamental frequency, f, by adding scaled cosine and sine waves with frequencies: f, 2f, 3f, 4f, etc.
