A Non-Sinusoidal Periodic Signal

If the frequencies of the added sinusoids are integer multiples of the fundamental, the resulting signal will be periodic.

Figure 2: Adding sinusoids at 3, 6, 9 Hz produces a periodic signal at 3 Hz.

Sinusoidal components, or partials that are integer multiples of a fundamental are calle harmonics.
