| Abstract: | This paper proposes a method of realizing an arbitrary waveform generator based on Direct Digital Synthesis.The arbitrary waveform＇s amplitude data and control parameters are accessed through VB6.0,and the microcontroller 89C52 is used to control the arbitrary waveform＇s Direct Digital Synthesis、storage and D/A conversion.Because the proposed waveform generator＇s type,amplitude and frequency can easily be programmed and the system uses a microcontroller to achieve the DDS,it becomes a high-precision,cost-effective and flexible waveform generator. |
