摘要： A method and a device for creating a calibrated periodic analogue signal with pre-determined frequency components are disclosed. According to the invention, uncalibrated digital data are calculated using the pre-determined frequency components, said data are converted into an analogue signal, parameter values of the output signal are determined and should the parameter values exceed a threshold value a correction value for the digital data is determined.
