Abstract
In a method for the production of a radio-frequency signal modulated as a function of a low-frequency digital data stream, a clock signal is provided having a frequency that is at least four times as high as the frequency of the radio-frequency signal to be produced. The clock signal is used for mixing the low-frequency data stream with a cyclical numeric sequence representing a continuous sinusoidal or co-sinusoidal series. A circuit arrangement implements such a method to produce a radio-frequency signal modulated as a function of a low-frequency digital data stream, and a magnetic resonance tomography system employs such a circuit arrangement.
