DEFINITION

Classification: 369/44.35

Servo loop gain/switching control:

(under subclass 44.11) Subject matter wherein the servo system varies the servo gain or switches in/out or between servo loops.

(1) Note. Varying the gain also includes techniques for stabilization.

(2) Note. Varying the gain may be implemented with either active or passive (e.g., notch filter etc.) elements.

(3) Note. Gain is defined as the ratio of output power to input power of a system or component.
