loop gain


  • WordNet 3.6
    • n 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"

This is enough for John, who has now gained his feet, and throws aside the entangling loop.
"Miss Caprice" by St. George Rathborne
Will cut the loop, and the horse, feeling himself disembarrassed, made a desperate exertion, and succeeded in gaining the bank.
"Border Raids and Reivers" by Robert Borland

Process control authority Béla Lipták answers a reader's question regarding PID loops and if they can be used without having to change the loop gain when the number of pumps used is changed.
Loop gain in aluminum extrusion processes.
As noted earlier, there are productivity gains if a portion of the seamless market can be converted to double-needle-bar warp knitting when the loop production rate is higher for a warp-knitting approach than for a weft-knitting approach.
On Friday, Cargill announced plans to add a rail loop at its grain elevator in Tuscola, Ill. To gain access to CSX Transportation.
The selection of the ranges for the valves in split- range operation should be based on keeping the loop gain constant.
The Wyoming Department of Transportation Thursday lost its fight to gain a wider right of way for the planned west belt loop around Casper.

In science:

In “timing” mode the series noise reduces by almost a factor of 2, because of the larger transconductance of N1 which gives a larger loop gain.
CLARO-CMOS, a very low power ASIC for fast photon counting with pixellated photodetectors
Set the EMCCD camera frame rate and electron multiplication gain to match the brightness of the tip-tilt guide source. A frame rate of 300 Hz is preferred (for a control-loop correction bandwidth of ~30 Hz), but can be lowered as necessary for fainter objects at the cost of lower quality tip-tilt correction. 5.
Bringing the Visible Universe into Focus with Robo-AO
For such a randomly placed vortex loop, which relieves strains by allowing spin rotations of order 2π , the system can typically gain disorder energy Edisorder ∼ Lθ ∼ L.
Smectic Liquid Crystals in Random Environments
We now need to estimate the pinning energy gain from introducing a dislocation loop and optimizing its configuration, analogously to the analysis for a vortex loop above.
Smectic Liquid Crystals in Random Environments
Valence bonds gain energy by “resonating” in pairs (Anderson, 1987; Fazekas and Anderson, 1974; Pauling, 1949; Rokhsar and Kivelson, 1988); shown are resonances around the plaquette (i.e. square loop) marked with a star.
