Passive transmission refers to the transfer of energy or information without the need for an active intervention by the transmitter. In various systems, this process occurs when a signal, energy, or data is relayed through natural means, without external power or control.

This concept can be observed across different fields, from telecommunications to biological processes. Understanding the mechanisms behind passive transmission is crucial for optimizing system performance and minimizing loss or inefficiency.

Passive transmission relies on environmental or inherent properties, such as wave propagation, resistance, or diffusion, to transfer signals or energy.

  • In telecommunications, passive transmission often occurs through fiber optics, where light signals travel over long distances with minimal energy loss.
  • In biology, passive transmission can be seen in the movement of molecules across cell membranes via diffusion.
  • In electrical systems, passive components like resistors and capacitors transfer signals without adding energy to the system.
