Abstract:
1. A conversion device comprising: a waveform-data-string storage unit that stores therein a waveform data string including a plurality of digital values; a control-data storage unit in which operation-mode specifying data that specifies an operation mode and update request data are written; a digital-value output unit that, when the operation-mode specifying data specifies a first operation mode, while sequentially updating an address to be read in the waveform-data-string storage unit to an address where a subsequent digital value is stored for each output period set in advance, sequentially reads and outputs the digital value that constitutes the waveform data string from the address to be read for the each output period and that, when the operation-mode specifying data specifies a second operation mode, while updating the address to be read at a timing when the update request data is written, reads and outputs the digital value that constitutes the waveform data string from the address to be read; and a D/A conversion unit that converts the digital value output by the digital-value output unit into an analog value.
