15. A method for galvanically isolating an information signal, the method comprising:
-
providing an electrically-isolating acoustic coupler comprising an electrically-isolating film acoustically-coupled transformer (FACT);
providing a carrier signal;
modulating the carrier signal with the information signal to form a modulated electrical signal;
acoustically coupling the modulated electrical signal through the electrically-insulating acoustic coupler; and
recovering the information signal from the modulated electrical signal acoustically coupled through the electrically-isolating acoustic coupler. - View Dependent Claims (16, 17, 18, 19)
