Abstract

Disclosed is a transmitting device comprising two galvanically isolated sub-circuits. The first sub-circuit comprises: a carrier signal source for outputting a carrier signal; a digital signal source for outputting binary signal levels; and a logic component for performing an AND operation on two input signals. The second sub-circuit comprises: a signal input; a signal output; and a first RC element, the signal input, the signal output and the RC element being connected in parallel to one another with respect to a second reference potential. A first isolating capacitor is connected between the first logic output and the signal input for galvanic isolation. A second isolating capacitor is connected between the first reference potential and the second reference potential for galvanic isolation.
