Noun1.loop gain - (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"
amplification, gain - the amount of increase in signal power or voltage or current expressed as the ratio of output to input
telecom, telecommunication - (often plural) systems used in transmitting messages over a distance electronically

Sliding mode control for the high-performance class-D audio amplifier provides higher loop gain across the audio frequency band and avoids the use of differentiators which are prone to high frequency noise.
It can be seen that there is a limit range for the closed loop gain in Figure 5.
An integrated loop gain linearization model transforms individual mechanical furnace characteristics and uniforms the control loops.
In addition, as the magnitude of the inner loop gain [K.
Second, the drop causes the open-loop bandwidth and loop gain to drop as well, resulting in higher distortion and slower dynamics.
2-bit voltage selector pins allowing 90, 115, 170, and 240 V outputs, via a DC/DC step-up converter and internal loop gain.

In addition, by using voltage-mode PWM leading-edge modulation with non-linear control and input voltage feed-forward compensation, the ISL8115 maintains a constant loop gain for optimal fast transient response.
The model can be equivalent to a Miller FD, and its locking range is determined by the frequency range where the loop gain exceeds one [13].
In theory the 6-wire remote sense configuration removes all errors except for the finite loop gain error and the input offset error associated with the current meter.
0]) is measured between signal input and output points, so it will be different for different input and output positions, but the Open Loop Gain (OLG = DG * H(J[omega])) will keep invariant.
