Abstract :
This paper describes an original experimental procedure to extract the oscillator´s phase sensitivity to injected noise perturbations. The proposed method relies on measuring the width of the locking ranges over which the oscillator´s response synchronizes with an injected small-amplitude signal. The extraction procedure is applied to a relaxation oscillator which exhibits a strongly nonlinear behavior.
