Notes on and illustrations of Fourier superposition of discrete frequency sinusoids and of continuous frequency sinusoids fourier_wiki.ppt

The first part of the notes are the introduction to the activity above, superposing waves of frequencies that are an integer multiple of some fundamental frequency. The second part relates to the creation of a pulse by the superposition of waves with all possible frequencies. Often the activity on the discrete superposition eats up all the time available.
