ABSTRACT:
A first converter circuit converts a state signal, whose level is constant or slowly varies during a predetermine period of time, into a pulse signal to allow the signal to propagate across an electrically insulating area. A second converter circuit converts the pulse signal, which has propagated through an insulating circuit, into the original state signal or a signal having the same characteristics as the original state signal.
