Abstract:
An apparatus for generating coded high-frequency signals, comprising:a converter for converting a non-electrical primary energy into low-frequency electrical energy; an element with a non-linear characteristic curve having a behavior that changes abruptly as a function of applied voltage starting from at least one of a specific limit value and a limit range, the element thereby generating a current pulse with a steep edge which corresponds to a high-frequency signal, the element thereby converting the low-frequency electrical energy into high-frequency electrical energy in the form of the high-frequency signal; a coding device for generating a coded signal from the high-frequency signal; and a filter for selecting a narrow signal from the high-frequency electrical energy, the filter being connected between the element and the coding device.
