ABSTRACT:
A circuit arrangement for retrieving data contained in binary data signals contains an integration stage that at least partially integrates and limits the binary data signals an outputs sample signals to a following phase control circuit, the sample signals being allocated to the integrated and limited data signals. The integration stage outputs further data signals allocated to the integrated and limited data signals to a decoder stage which retrieves the data by use of reference signals output by the phase control circuit. The time constant in the integration and the pulse duration of the sample signals are varied according to the frequency of the reference signals output by the oscillator. They are varied by use of switch stages that are designed in correspondence with an oscillator in the phase control circuit.
