Modulated Signals in Chemical Reaction Networks
arXiv - CS - Emerging Technologies Pub Date : 2020-09-14 , DOI: arxiv-2009.06703
Titus H. Klinge, James I. Lathrop

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.

化学反应网络中的调制信号

电气工程和分子编程具有许多相同的数学基础。在本文中,我们展示了如何使用电气工程中的调制和解调技术通过一对化学物质发送多个信号。我们构建的关键是,我们提供经典线性带通和低通滤波器的化学实现,其感应微分方程与其电气工程对应物相同。我们展示了如何调制具有不同载波频率的 \emph{任意} 独立输入信号,以便通过共享介质进行传输。然后可以使用带通和低通滤波器隔离和解调介质中的特定信号。
