Class Information
Number: 330/110
Name: Amplifiers > Signal feedback > Nonlinear impedance element in loop path
Description: Subject matter wherein the "loop path" (see (3) Note under subclass 75 for the definition of loop path) includes a nonlinear impedance circuit element, which may be resistive, capacitive, or inductive, and whose impedance is such for changes in voltage applied thereto that the relationship between the voltage across such element to the current flow through the element is nonlinear.
