insertion loss

[in′sər·shən ‚lȯs]
(electronics)
The loss in load power due to the insertion of a component or device at some point in a transmission system; generally expressed as the ratio in decibels of the power received at the load before insertion of the apparatus, to the power received at the load after insertion.

insertion loss

The amount of loss attributed to a particular device being used in (inserted into) the system. For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss.
