Abstract:
1. A method for transmitting data via a transmission path with at least two inductive transformers which each respectively include a primary winding with a time constant and a secondary winding, the method comprising: actuating the primary windings to transmit an information event using actuating signals such that the sum of the actuating signals follows an envelope with an envelope time; wherein the envelope includes a time profile that rises within a rise time from an initial value to a maximum value and falls within a fall time from the maximum value back to the initial value, and the rise time and the fall time are longer in terms of absolute value than the time constants of the primary windings; wherein the time profile of the actuating signals is dependent on information to be transmitted and is such that there is at least one steep edge present whose edge time is shorter than the time constants of the primary windings; and producing the steep edge of the actuating signal for one of the primary windings after a magnetization time for the one of the primary windings through partial off-commutation of the one of the primary windings during an off-commutation time.
