摘要： A digital waveform generating circuit having a DC voltage as an input and generating a sinusoidal digital signal, an active filter extracting low-frequency components from the sinusoidal digital signal generated in the digital waveform generating circuit, and a high-voltage control circuit generating a high-voltage drive signal using the sinusoidal digital signal after passing through the active filter are provided. A smooth waveform without steep voltage changes is generated.
