Abstract: An exemplary energy supply device for explosion-proof electronic functional units supplies each functional unit with a high-frequency AC voltage via an inductor. The inductors are formed as substantially congruent conductor tracks of a multi-level printed circuit board, which can be connected to one another and arranged vertically on a distribution printed circuit board. The number of metallization planes of the multi-level printed circuit board being greater than the number of metallization planes of the distribution printed circuit board.

Abstract: Exemplary embodiments relates to a demodulator for frequency-shift keyed signals by using the Goertzel algorithm according to the general recursive calculating rule, where c re = 2 * cos ⁡ ( 2 * π * f g f s ) with the sampling frequency fs and the specified frequency fg. To reduce the mathematical complexity in feed-power-limited devices, it is proposed that the sampling frequency fs is an integral multiple of the frequency fg of a specified discrete spectral component.

Abstract: An exemplary energy supply device for explosion-proof electronic functional units, in which the functional units are supplied from a high-frequency AC voltage that is individually output for each of the functional units via an inductor. In order to supply a multiplicity of functional units with little effort, the multi-level printed circuit board of each inductor can be covered with a flat board of magnetic material. The flat board being parallel to a plane of conductor tracks of the inductors.

Abstract: An exemplary energy supply device for explosion-proof electronic functional units includes a plurality of inductors. The functional units are supplied from a high-frequency AC voltage that is individually output for each of the functional units via an inductor. In order to supply a multiplicity of functional units with little effort, the multi-level printed circuit board of each inductor is at least partially covered with a flat board of a magnetic material parallel to the plane of its conductor tracks.
