摘　　要：正弦振荡器被广泛应用于电子技术中,而基于DSP技术的正弦振荡器具有许多优点.本文利用数值迭代方法,在建立输出为正弦序列的离散系统模型的基础上,在CCS环境中通过定时器、主函数和中断等关键技术的设置完成了整体程序设计后,通过数字振荡器DSP的实现原理即可获得正弦波振荡器;通过仿真,能得到设定参数的正弦序列输出,达到了设计目的,并具有调整方便灵活、分辨率高等特点.The sinusoidal oscillator is widely applied in the various fields of electronic technology. Compared with the traditional analog sinusoidal oscillator, the sinusoidal oscillator based digital signal processing technology is more excellent. In this article, after the model of a discrete system which can generate predefined sine series is created by numerical iteration, and the integral programs are completed by the proper sets of timers, main functions and interrupts in Code Composer Studio （CCS）, the sinusoidal oscillator by digital signal processing is obtained. By the simulation results, the predeiined sine series can be obtained and the design object is fulfilled. Besides its high resolution, the sinusoidal oscillator based digital signal processing technology present many other characteristics, such as convenience and mobility for adjustment.
