ABSTRACT:
An arrangement for converting a multiphase electric signal into a frequency is disclosed. Illustratively, the arrangement comprises an adder circuit for adding the individual phases comprising said multiphase signal. The arrangement also comprises one first polarity reversing switch for each phase in the multiphase signal. A voltage/current converter is connected downstream of the first polarity reversing switches. At least one second polarity reversing switch is connected downstream of the voltage/current converter. A control circuit generates a periodic switch-over signal for controlling the first and second polarity reversing switches. In addition, a constant current source is connected to an input of the second polarity reversing switch.
