Abstract:
1. A digital/analog (D/A) converter comprising: a wave-form data-array memory for memorizing a wave-form data array configured of a plurality of digital values; a wave-form output-format data memory for memorizing wave-form output-format data designating a wave-form output period; a digital value outputter for sequentially reading out the digital values for the wave-form output period from the wave-form data-array memory and outputting the digital values; and a D/A converter for converting the digital values outputted for the wave-form output period from the digital value outputter into analog-data values, wherein the digital value outputter determines whether a wave-form output request or a wave-form output-stop request is accepted for a D/A conversion period, and when the digital value outputter determines that the wave-form output request is accepted, the digital value outputter performs the reading out and outputting of all of the digital values in the wave-form data array previously written into the wave-form data-array memory, while when the digital value outputter determines that the wave-form output-stop request is accepted, the digital value outputter stops performing the reading out and outputting of the digital values.
