TWO-POINT MODULATOR ASSEMBLY

摘要

The invention relates to a two-point modulator assembly (10), which has been improved in relation to conventional two-point modulators in such a way that the high-pass coupling point of the modulator, which comprises a phase-locked loop (12, 14, 16, 18), is formed by an extended loop filter (14). In accordance with the inventive principle, the extended loop filter (14) comprises a coupling member, in which the modulation signal is combined with the output signal of a phase comparator (12). A voltage-controlled oscillator (16) comprising only one tuning input can thus be used in an advantageous manner.
