Claim Text:
1. An apparatus for generating sinusoidal waves, comprising: a look-up table storage unit configured to include a plurality of sampling points with respect to abase frequency; a waveform-synthesizing unit configured to calculate an integer ratio between an input target frequency and the base frequency and loading at least some of the plurality of sampling points from the look-up table storage unit according to the integer ratio; a correction unit configured to substitute a digital value of at least one sampling point among the sampling points loaded from the look-up table with a digital value of a sampling point among the plurality of sampling points included in the look-up table storage unit having a maximum value; and a sinusoidal wave generation unit configured to generate sinusoidal waves using the sampling points changed by the correction unit.
