The frequency source provides a pulse output signal (SO) with a specific pulse frequency using an active measuring transducer (H) detecting a frequency-dependent measuring parameter and controlling a semiconductor switch (T) connected between a reference terminal (RT) and a supply and signal terminal (FST). The transducer may be provided by a Hall element coupled to the supply and signal terminal via a diode (D) and connected in parallel with a charge accumulator (ACK) for ensuring a continuous voltage supply. |
