<p>A method and apparatus to generate harmonics. The method of generating the harmonics includes selecting a first coefficient and a second coefficient according to a result of comparing a level of an input frequency signal and a level of a feedback signal, adding a result of multiplying the level of the input frequency signal by the first coefficient and a result of multiplying the level of the feedback signal by the second coefficient to calculate the level of an output frequency signal, delaying the output frequency signal having the calculated level by a predetermined sample, and transmitting a resulting level of the delayed output frequency signal as the level of the feedback signal.</p> |
