If you are unclear about the meaning of e^jwt, I suggest that you first look at the Complex Number Tutorial on this website. If you are unclear about the Fourier series as a sum of sine waves and cosine waves, look at the Tutorial on that in this website.
|Flash Program Description||Complex Fourier Series Program|
|This flash program shows the Fourier series as represented by a sum of complex exponentials. it assumes that you already have a good handle on the Fourier Series as a sum of sine waves and cosine waves. It also assumes that you have a good handle on complex numbers and phasors.||click me|
