ABSTRACT:
In a circuit arrangement for deriving a binary signal from an alternating voltage (U), in which the alternating voltage can be delivered via a capacitor to the input of a threshold value circuit and a reference voltage obtained by integration serves to adjust the operating point at the input, an up/down counter is provided for deriving the reference voltage, its counting direction being controllable by the binary signal. From the output signal of the up/down counter, a further binary signal is derived, which after integration forms the reference voltage. The circuit is suitable for use in evaluating the data subcarrier component of a Radio Data System (RDS) signal, as defined by European Broadcasting Union (EBU) Technical Standard 3244-E.
