SINUSOIDAL WAVE GENERATION APPARATUS, SINUSOIDAL WAVE GENERATION METHOD, AND PIEZO ACTUATOR DRIVING SYSTEM USING SAME

摘要

The present invention relates to a sinusoidal wave generation apparatus, a sinusoidal wave generation method, and a piezo actuator driving system using the same. According to an embodiment of the present invention, the sinusoidal wave generation apparatus comprises: a look-up table including multiple sampling points for a reference frequency and a sampling frequency; a resolution expansion unit to load the sampling points at a predetermined cycle according to an input signal and to output interval value data among the loaded sampling points and the sampling points by calculating the interval value data; and a sinusoidal wave generation unit to generate a sinusoidal wave using the sampling point and the interval value data.;COPYRIGHT KIPO 2015
