A method for the detection of a coil (L) in an electronic circuit, which is operated with a direct voltage (Ub) lying in a prescribed voltage range, and in which the coil (L) together with a condenser (C1) forms an electrical oscillating circuit, comprising the step where the electrical oscillating circuit is excited with a pulse, which during the oscillation temporarily generates a voltage value lying outside the prescribed voltage range at a first coil terminal (S1) that can be tapped on the coil (L), and in that this voltage value is ascertained.
An arrangement for the detection of a coil (L) in an electronic circuit operated with a direct voltage (Ub) in a prescribed voltage range, with a coil (L) and a condenser (C1), which form an electrical oscillating circuit, comprising a first coil terminal (S1) of the coil (L) connected to a pulse generator (P3, D1) for the generation of a pulse and has a voltage detector (P4, D1) for the detection of a voltage value lying outside the voltage range of the direct voltage (Ub).
