Information about Transmission System
- See Transmission (mechanics) for a car's transmission system
Some transmission systems contain repeaters, which amplify a signal prior to re-transmission, or regenerators, which attempt to reconstruct and re-shape the coded message before re-transmission.
One of the most widely used transmission system technologies in the Internet and the PSTN is SONET.

A regenerative heat exchanger is a type of heat exchanger where the flow periodically reverses directions. This type of heat exchanger can have thermal efficiency as high as 95% to 99%, transferring almost all the relative heat energy from one fluid flow to the other.
