<P>PROBLEM TO BE SOLVED: To provide a signal waveform generation circuit which can reduce the size of a circuit scale. <P>SOLUTION: The signal waveform generation circuit has: a data table 5, which stores the waveform data of a sinusoidal signal; a complement table 6 which memorizes correction data for correcting the signal level of the sinusoidal signal; a data table reference portion 32 which reads out the waveform data from the data table 5 and generates the sinusoidal signal; a complement table reference portion 111, which complements the waveform data read out from the data table 5 with the complement data of the complement table 6 and generates the sinusoidal signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
