The Fourier series representation has three different forms: Exponential (or the complex exponential) Trigonometric. Polar.
Complex Fourier Series is almost the same as Real Fourier Series, just rewriting sines and cosines using eulers number. The benefit is that now it could consider imaginary numbers as well as deal with a single coefficient term c rather than dealing with two coefficient terms.
Complex exponential form of a Fourier series an cos 2nt T + bn sin 2nt T .
Coefficients of complex Fourier series A straightforward computation gives c0 = a0, ,cn = (bn ian)/2, cn = (bn + ian)/2, n = 1,2,3,
The complex Fourier series obeys Parsevals Theorem, one of the most important results in signal analysis. This general mathematical result says you can calculate a signals power in either the time domain or the frequency domain.
