Abstract
In order to output an accurate waveform in which quantization noise has been cancelled out, provided is a signal generating apparatus that outputs an output signal corresponding to a waveform data sequence expressing a waveform, the signal generating apparatus comprising a DA converting section that outputs an analog signal by sequentially performing digital/analog conversion on each piece of data included in the waveform data sequence, at a timing of a sampling clock; and a jitter injecting section that injects jitter decreasing a quantization noise component of the output signal, into the sampling clock supplied to the DA converting section.
