摘　　要：提出了一种基于DSP数字振荡器产生移相正弦波的设计方法。系统由TMS320VC5416最小系统和两片TLC320AD50C及简单外围电路构成。简要介绍了系统的软硬件的设计方法。通过DSP数字振荡器的实现原理得到设定参数的两路移相正弦波输出,达到设计目的。实验结果表明该系统具有结构简单,频率相位调整方便灵活、分辨率高等特点。A kind of phase shifting sine wave generator based on DSP digital oscillator is designed. The system is consisted of TMS320VC5416 minimum system and two TLC320ADSOC chips and simple peripheral circuits. The system software and hardware design are introduced briefly in this paper. Two predefined phase shifting sine waves can be obtained by DSP digital oscillator technology and the design objective was fulfilled. The experimental results show that the system has the characteristics of simple structure,convenience and flexible for frequency and phase adjust and high-resolution.
