ABSTRACT:
A circuit is described for producing an alternating voltage in an electronic device which is remotely fed over a digital transmission path. By the pulses of a clock (8) two capacitors, C1, C2 are charged via a transistor (T1) and a transformer (10), one of them (C2) being discharged over a parallel resistor (R2). A coupling capacitor (CK) which is charged by the other capacitor (C1) is discharged alternately by the influence of the dischargeable capacitor (C2) over a transistor (T2).
