The Same Idea works for the compensation for nonlinearities Example and demo: Amplifier with a deadzone (t) (t) EK, y(t) The second system in the forward path has a nonlinear input-output relation (a deadzone for small input), which will cause distortion if it is used as an amplifier. However, as long as the amplitude of the "loop gain is large enough, the input-output response= 1/K,The Same Idea Works for the Compensation for Nonlinearities Example and Demo: Amplifier with a Deadzone The second system in the forward path has a nonlinear input-output relation (a deadzone for small input), which will cause distortion if it is used as an amplifier.
