Fourier synthesis is nothing else than the summation of cosine and sine waves at different frequencies and amplitudes. For a signal of infinite duration, the Fourier spectrum is discrete and reduces to the summation of harmonics. The values of the coefficients are usually displayed as a line spectrum, where each line indicates the size of a particular coefficient.

This simulation allows to adjust the first seven coefficients of the Fourier series (both for the cosine and the sine terms). In addition, a few predefined wave forms can be selected.
