loop gain

[′lüp ‚gān]
(control systems)
The ratio of the magnitude of the primary feedback signal in a feedback control system to the magnitude of the actuating signal.
(electronics)
Total usable power gain of a carrier terminal or two-wire repeater; maximum usable gain is determined by, and may not exceed, the losses in the closed path.
