The amplitude and phase lag at the maximum value are the polar coordinates of one harmonic in the Fourier series expansion of the square wave. The corresponding rectangular coordinates can be determined by evaluating the cross-correlation at just two phase lags separated by 90º. See more A Fourier series is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series. By expressing a … See more This table shows some mathematical operations in the time domain and the corresponding effect in the Fourier series coefficients. Notation: See more Riemann–Lebesgue lemma If $${\displaystyle S}$$ is integrable, $${\textstyle \lim _{ n \to \infty }S[n]=0}$$, Parseval's theorem See more The Fourier series can be represented in different forms.
