Abstract: A method for generating a pulse, wherein a predetermined first limit curve and a predetermined second limit curve are defined for a pulse shape of the pulse, wherein the limit curves describe the change over time of a current variable, and wherein the second limit curve runs entirely within the first limit curve. As a pulse shape for the pulse, a curve plotted between the limit curves is generated, which, in comparison with a rectangular pulse plotted between the limit curves, in a first area of the current variable facing away from an extremum, is deformed toward the first limit curve and which, in a second area of the current variable facing toward the extremum, is deformed toward the second limit curve.
