There is an equation for calculating Fourier series coefficients. You should be able to find it in either your text book or class notes.

The equation will be near the beginning of wherever your textbook first begins discussing Fourier series. It involves doing an integral -- if f(t) is the signal, look for something sort of like this in the equation:


\int f(t) \cdot \sin(\frac{2 \pi}{T}t) \ dt


or a similar expression with cos instead of sin.

Please look in your book, wherever it begins discussing Fourier series.

Just scan the book for the terms "fourier series coefficients".

Thanks for the great explanation... On where it might be in a textbook. ***

For a start what is the constant fourier coefficient: what is the mean value of the function?
