Summary: This module discusses the Fourier series encoding scheme.

We can create an encoding
scheme in the frequency domain to represent an alphabet
of letters. But, as this information-encoding scheme stands, we
can represent one letter for all time. However, we note that
the Fourier coefficients depend *only *on the
signal's characteristics over a single period. We could change
the signal's spectrum every

In this Fourier-series encoding scheme, we have used the fact
that spectral coefficients can be independently specified and
that they can be uniquely recovered from the time-domain signal
over one "period." Do note that the signal representing the
entire document is no longer periodic. By understanding the
Fourier series' properties (in particular that coefficients are
determined only over a
