The efficient propagation of signals through any transmission line requires a delicate balance between energy costs associated with squeezing a pulse by charging/discharging capacitors, information theoretical costs associated with packing in pulses as closely as possible, and fidelity costs associated with minimizing interfering overlaps between signals. We will explore the energy trade-offs in neurobiological systems such as axons that act as 1-D transmission lines equipped with a series of amplifiers (ion channels) and batteries (ion pumps). We will then extend the concepts of pulse shaping for low-energy propagation to body sensing networks communicating using 2-D transmission lines distributed through the humans kin, and formulate analogous principles for nanoscale interconnects with significant quantum corrections.
