Abstract
A method and apparatus for processing in output of an inductive sensor, including integrating the output of the inductive sensor with an integrator, having a transfer function with at least two zeros, and at least three poles having characteristic frequencies above the zeros, having a greater number of said poles than said zeros, wherein an integration is performed at frequencies above the characteristic frequencies of the poles, and low frequency noise is substantially rejected at frequencies below the poles. The inductive sensor may be, for example, a Rogowski coil.
