loop gain

Also found in: Dictionary, Thesaurus, Wikipedia.

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.
