Query: Modulated Signals in Chemical Reaction Networks   Electrical engineering and molecular programming share many of the same
mathematical foundations. In this paper, we show how to send multiple signals
through a single pair of chemical species using modulation and demodulation
techniques found in electrical engineering. Key to our construction, we provide
chemical implementations of classical linear band-pass and low-pass filters
with induced differential equations that are identical to their electrical
engineering counterparts. We show how to modulate \emph{arbitrary} independent
input signals with different carrier frequencies for transmission through a
shared medium. Specific signals in the medium can then be isolated and
demodulated using band-pass and low-pass filters. Such programmable chemical
band-pass filters also offer a way to monitor chemical systems to verify that
they are operating between a prescribed set of frequencies.
