ABSTRACT:
A modulation circuit that outputs modulation signals, comprising: a memory circuit that stores waveform data that determines the time width of a portion of a modulation signal, the portion being adjusted to a predetermined amplitude value, the waveform data being stored in such a manner as to output a plurality of modulation signals; and a circuit that generates the modulation signals, based on the waveform data and input gradation data.
