Abstract
A circuit arrangement with a data sequence generator for the generation of an oscillator signal as a sequence of digital data, and having the following circuit parts: a first multiplication unit driven by a first auxiliary signal and a first control signal, where the first control signal corresponds to the sine of a manipulated variable that determines the frequency of the oscillator signal; a second multiplication unit driven by a second auxiliary signal, where the second control signal corresponds to the cosine of the manipulated variable; a third multiplication unit driven by a third auxiliary signal and a third control signal, where the third control signal corresponds to the sum of the first and second control signal; a first adding unit driven by the first multiplication unit and third multiplication unit; a second adding unit driven by the first multiplication unit and the second multiplication unit; a first time-delay unit driven by the first adding unit, where the oscillator signal is provided as a third auxiliary signal at the output of the first time-delay unit; a second time-delay unit driven by the second adding unit, where the second auxiliary signal is provided at the output of the second time-delay unit; a weighting unit for weighting the third auxiliary signal with a factor of 2, and, a third adding unit driven by the second time-delay unit and the weighting unit, where the first auxiliary signal is provided at the output of the third adding unit.
