in fig3 this means that the series of control values vc must be such that avg vc lt vin 2 n u2212 m in order to compensate for the net positive overshoot that is observed calibration table 5 stores for each input value in the subset of input values requiring dithering over a major transition a suitable series of control values vc which generate a raw voltage trace uraw t whose average avg uraw t is equal to the desired output voltage f vi of equation it must be noted that the stored series of control voltages would not generate the desired output voltage f vi if the dac 2 did not generate an overshoot undershoot at the respective major transition in other words the condition equation is not fulfilled for the series stored calibration table 5 advantageously the series of control values vc stored in calibration table 5 comprises values that differ by more than 1 for example if a strong overshoot as shown in fig3 occurs when switching between vc 1 and vc 2 as defined by equation the series of control values can comprise additional values vc 3 vc 1 u2212 4 and a sequence vc 1 vc 3 vc 2 as shown in the.
