Abstract
In an electro-surgical high-frequency generator, the signal frequency or the modulation frequency or a clock frequency or any combination thereof are modulated using a low-frequency modulation signal in such a way that the spectra thereof are widened. This results in a reduction of interference on peripheral devices.
