Gain clamping, also called gain pinning, holds an optical amplifier's gain fixed, often stabilizing erbium-doped fiber amplifiers as WDM channels change; first proposed in 1991.
Gain flattening filter
A gain flattening filter, also called a gain-equalizing filter, is a passive optical filter that equalizes the gain of optical amplifiers, chiefly EDFAs, in wavelength-division multiplexed systems.
Gain margin
Gain margin is a control-systems measure of how much a feedback loop's gain can increase before the closed-loop system becomes unstable, usually expressed in decibels.
Gain scheduling
Gain scheduling is a control engineering technique that controls nonlinear or time-varying systems with a family of linear controllers whose gains adjust automatically with measured scheduling variables.
Gait phase detection
Gait phase detection identifies the phase of the walking cycle a person or legged robot is in, distinguishing stance from swing and locating heel strike and toe off.
