<P>PROBLEM TO BE SOLVED: To provide a reference signal generator for precisely estimating self-propelled DAC values even if variations occur to stable transition curves based on starting characteristics. <P>SOLUTION: A control section 10 calculates an estimation curve 201 with an interval MN to specific time from estimation timing t<SB>N</SB>of the self-propelled DAC value as a reference interval when the estimation timing t<SB>N</SB>of the self-propelled DAC value is reached. The control section 10 obtains a synchronization DAC value of a correction interval LM differing from the reference one MN, and calculates a difference value ΔD to an estimation synchronization DAC value obtained from the estimation curve 201. The control section 10 calculates a correction value Cd based on the difference value ΔD, and corrects each synchronization DAC value by the correction value Cd to obtain a correction synchronization DAC value. The control section 10 calculates a new estimation curve from the synchronization DAC value including the correction synchronization DAC value, and estimates the self-propelled DAC value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
