Abstract
A method for reducing a current crosstalk interference component from an oscillating multiplex electric current flowing through a magnetic coil of a given electrical circuit originated from an electromagnetic flux emanating from a magnetic coil of a certain neighboring electrical circuit and intercepted by the magnetic coil of the given electrical circuit. The oscillating multiplex electric current has a main current component, related to the given electrical circuit, which is superposed with the current crosstalk interference component. The reduction of the crosstalk interference is achieved by estimating the current crosstalk interference component induced by the certain neighboring electrical circuit, and subtracting this current crosstalk interference component from a multiplex electric current flowing through the magnetic coil of the given electrical circuit by using earlier obtained crosstalk interference estimates.
