Abstract
A two-point modulator arrangement is specified, said arrangement being developed with respect to conventional two-point modulators to the effect that the high-pass coupling-in point of the modulator that comprises a phase locked loop is formed by an expanded loop filter. In accordance with the present principle, the expanded loop filter comprises a coupling-in element, at which the modulation signal is combined with the output signal of a phase comparator. A voltage-controlled oscillator having only one tuning input can thus advantageously be used.
