When viewing in the frequency domain, a ``spike'' at a frequency
indicates there is a sinusoid in the signal at that frequency.
Figure 3:
Adding sinusoids at 5, 10, 15 Hz
in both time and frequency domain.

The height of the spike here, indicates the amplitude (thus all
sinusoids here have a peak amplitude of 1).
The harmonic relationship between the partials can be seen by
the even spacing between the ``spikes''.
