Loop Gain (Noun)
Meaning
(telecommunication) the gain of a feedback amplifier or system as a function of how much output is fed back to the input; "if the loop gain is too great the system may go into oscillation".
Classification
Nouns denoting attributes of people and objects.
Examples
- The loop gain in this circuit must be carefully adjusted to prevent it from entering into an unstable oscillation mode.
- To determine the stability of the system, we first need to calculate the loop gain over its operating frequency range.
- A high loop gain in a feedback amplifier can cause an increase in sensitivity but may also lead to frequency instability.
- The designer needs to control the loop gain so that the system operates in a stable manner under all anticipated operating conditions.
- If the loop gain is too great the system may go into oscillation, resulting in an unstable and potentially destructive condition.
