%X This paper discusses the mirror image interference in direct digital waveform synthesis. The formation and distribution characteristics of mirror images are illuminated, and the impact of sampling rate which brings mirror image interference is analyzed. Based on these, the condition of sampling rate which results in mirror image interference is concluded and proved by experiment. The conclusion provides new theoretical basis on sampling rate selection in digital waveform synthesis.
