I know that a square or saw tooth wave consists of infinite amount of sinousoids each having different frequency and amplitude. But when I look at their plot they seem to have a well defined frequency or period. Which term in the Fourier series determines their frequency? Does a saw tooth or square wave have an uncertainty in its frequency? How can I calculate the frequency of such a wave?

Thanks for all the answers in advance!
