It is often possible to represent a periodic function f as a sum or series of cosine and sine functions. The idea is that a periodic signal, namely the function f, can be viewed as an overlay of many harmonic oscillations, namely of cosine and sine functions. Determining the individual harmonic oscillations corresponds to a decomposition of the periodic signal into its fundamental oscillations.

Determining the individual harmonic oscillations corresponds to a decomposition of the periodic signal into its fundamental oscillations.
