Editing Insertion gain

In [[telecommunications]], '''insertion gain''' is the [[Gain (electronics)|gain]] resulting from the insertion of a device in a [[transmission line]], expressed as the ratio of the [[signal]] [[Power (physics)|power]] delivered to that part of the line following the device to the signal power delivered to that same part before insertion. Gains less than unity indicate ''[[insertion loss]]''. Incident power is made of two part, the reflection from the device and the power absorbed by the device.<ref>{{cite web | url=https://www.techplayon.com/insertion-loss-return-loss/ | title=Insertion Loss / Return Loss | date=19 April 2017 }}</ref>

Insertion gain is usually expressed in [[decibel]]s.
